Pining for renewable resins was written by Doehle, Jens Adolf. And the article was included in European Adhesives & Sealants in 2003.Computed Properties of C10H22O3 This article mentions the following:

In response to the demand of environment friendly adhesives, solvent based adhesives using Elliotii rosins were assessed for open time duration on one-sided and two-sided applications. The open time with slightly modified rosin was two to three times longer than with a highly modified rosin. This could be attributed to the m.p. and longer open time led to less cohesion and heat resistance of the rosin. However, the highly modified rosin turned out to be the better choice, wherein the heat resistance of the test bodies with modified rosin was around 10° higher than with the slightly modified rosin. In the experiment, the researchers used many compounds, for example, rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6Computed Properties of C10H22O3).

rel-(1s,4s)-4-(2-Hydroxypropan-2-yl)-1-methylcyclohexanol hydrate (cas: 2451-01-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Computed Properties of C10H22O3

Effect of osmotic agent and vacuum application on mass exchange and qualitative parameters of osmotically dehydrated strawberries was written by Macedo, Leandro Levate;Correa, Jefferson Luiz Gomes;da Silva Araujo, Cintia;Vimercati, Wallaf Costa. And the article was included in Journal of Food Processing and Preservation in 2022.Recommanded Product: 149-32-6 This article mentions the following:

Sucrose is the most commonly used solute in the osmotic dehydration (OD) of fruits. However, there is increasing interest in replacing it with other alternative sugars. Polyols are carbohydrates with low glycemic, insulinemic, and cariogenic indexes. Therefore, this work aimed to study the influence of the type of osmotic agent (sucrose, erythritol, or maltitol) and vacuum application on mass transfer and phys. and nutritional changes in 10-mm edge strawberry cubes. OD was performed with or without vacuum application during the first 20 min in a total process time of 300 min. Higher solid gain, water loss and weight reduction, and lower water activity and moisture content were observed by using erythritol solution The vacuum application strengthened this behavior. The color of the samples was affected by factors. Osmotic processes reduced the total anthocyanin content (TAC), showing that leaching is an important qual. flow during osmotic processes. Novelty impact statement : Polyols showed good potential as an osmotic agent in the osmotic dehydration of strawberries and are a good alternative to the use of sucrose. Osmotic dehydration promoted a satisfactory impregnation of polyols in the strawberry, mainly with the application of vacuum, in which the mass exchange rates were increased. However, leaching was an important flow of anthocyanin loss from strawberries to the osmotic solution In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Recommanded Product: 149-32-6).

(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Recommanded Product: 149-32-6

Design and synthesis of novel α-aminoamides derivatives as Nav1.7 inhibitors for antinociception was written by Xue, Dengqi;Liu, Yani;Zheng, Yilin;Niu, Heling;Dong, Liying;Ouyang, Xiangshuo;Song, Siyu;Zhang, Denggao;Ge, Qianwei;Wang, Kewei;Shao, Liming. And the article was included in Chinese Chemical Letters in 2022.Formula: C8H9FO This article mentions the following:

Three novel series of α-aminoamides derivatives were designed and synthesized based on ralfinamide, and their Nav1.7 inhibitory activities were evaluated using manual patch clamp electrophysiol. Active compounds inhibited Nav1.7 with half maximal inhibitory concentration (IC₅₀) values ranging from 2.9μmol/L to 21.4μmol/L. Among them, the most potent compound I [R = 2H-1,3-benzodioxol-4-ylmethyl] exhibited about 12-fold potency better than ralfinamide. The investigation of their structure-activity relationship gives a strategy to improve the Nav1.7 inhibition of ralfinamide analogs. Compound I [R = 2H-1,3-benzodioxol-4-ylmethyl] was efficacious in antinociception in the mouse spared nerve injury (SNI) model of neuropathic pain without causing sedation in the open field test. In the experiment, the researchers used many compounds, for example, (S)-1-(2-Fluorophenyl)ethanol (cas: 171032-87-4Formula: C8H9FO).

(S)-1-(2-Fluorophenyl)ethanol (cas: 171032-87-4) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Formula: C8H9FO

Characterization of fragrant compounds in different types of high-salt liquid-state fermentation soy sauce from China was written by Li, Jingyao;Zhang, Mengli;Feng, Xiaojuan;Ding, Tingting;Zhao, Yue;Sun, Chengguo;Zhou, Shengli;He, Jing;Wang, Chunling. And the article was included in LWT–Food Science and Technology in 2022.Recommanded Product: 3391-86-4 This article mentions the following:

The aroma and sensory characteristics of 21 com. high-salt liquid fermentation soy sauces (HLFSS) suitable for different edible methods were investigated by MS-based non-targeted metabolomics workflow using headspace solid-phase microextraction gas chromatog./mass spectrometry (HS-SPME-GC-MS) combined with sensory evaluation. A total of 325 compounds were detected, and 60 were considered aroma-active compounds Light soy sauce (LSS) and premium soy sauce (PSS) for direct dipping contained more alcs. and esters. Aldehydes and furans were more abundant in dark soy sauce (DSS) used for stir-frying and braising. Principal component anal. (PCA) clustered LSS, DSS, and PSS into different quadrants and distinguished HLFSS of north-south origin. In addition, orthogonal partial least squares discriminant anal. (OPLS-DA) confirmed that the difference in volatile compounds of HLFSS in northern and southern China was related to local manufacturers use of the Japanese and Cantonese fermentation processes. Sensory evaluations showed that LSS and PSS had prominent alc. and fruit aromas, while DSS had firmer caramel and malty aromas. Aroma-active compounds influenced regional differences in sensory attributes. The present study results will provide a theor. basis for broadening industrial soy sauce production with different flavors. In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Recommanded Product: 3391-86-4).

Oct-1-en-3-ol (cas: 3391-86-4) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Recommanded Product: 3391-86-4

Potential low-calorie model that inhibits free fatty acid release and helps curcumin deliver in vitro: Ca²⁺-induced emulsion gels from low methyl-esterified pectin with the presence of erythritol was written by Yang, Jinyan;Wan, Li;Duan, Xingke;Wang, Hongdi;Yang, Zhixuan;Liu, Fengxia;Xu, Xiaoyun;Pan, Siyi. And the article was included in International Journal of Biological Macromolecules in 2022.Related Products of 149-32-6 This article mentions the following:

Our previous study showed that pectin de-esterified by high hydrostatic pressure assisted enzymic method (HHP-pectin) had better Ca2+-induced gel performance and more stable emulsion than those from conventional enzymic and alk. methods. In this study, Ca2+-induced emulsion gels were further prepared by HHP-pectin in the presence of erythritol, and their texture properties, moisture distribution, the release of free fatty acids (FFAs) and curcumin were investigated. Results showed that gel strength, gel elasticity, and water cut-off capacity of the prepared emulsion gels significantly increased with Ca2+ concentration increasing. Compared with emulsions, HHP-pectin emulsion gels can significantly decrease FFAs and curcumin release in vitro digestion, especially for samples with better texture properties (higher Ca2+ concentration). This study indicated that Ca2+-induced HHP-pectin emulsion gels prepared with erythritol may provide a new choice for low-calorie foods preparing, and may become a potential alternative model that inhibiting FFAs release and helping fat-soluble nutrients (curcumin) deliver. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Related Products of 149-32-6).

(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Related Products of 149-32-6

Selective skeletal editing of polycyclic arenes using organophotoredox dearomative functionalization was written by Ji, Peng;Davies, Cassondra C.;Gao, Feng;Chen, Jing;Meng, Xiang;Houk, Kendall N.;Chen, Shuming;Wang, Wei. And the article was included in Nature Communications in 2022.Recommanded Product: 2216-51-5 This article mentions the following:

A general organophotoredox approach for the chemo- and regioselective dearomatization of structurally diverse polycyclic aromatics, including quinolines, isoquinolines, quinoxalines, naphthalenes, anthracenes and phenanthrenes was described. The success of the method for chemoselective oxidative rupture of aromatic moieties relies on precise manipulation of the electronic nature of the fused polycyclic arenes. Mechanistic studies show that the addition of a hydrogen atom transfer (HAT) agent helps favor the dearomatization pathway over the more thermodynamically downhill aromatization pathway. This strategy was applied to rapid synthesis of biol. valued targets and late-stage skeletal remodeling en route to complex structures. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Recommanded Product: 2216-51-5).

And the article was included in Advanced Synthesis & Catalysis in 2022.Application of 873-76-7 This article mentions the following:

Switchable synthesis of aldehydes and carboxylic acids from alcs. by Pt-catalyzed H₂O₂ oxidation was performed for the first time using flow reactors. The use of an optimized amount of zero-valent Pt black diluted with SiO₂ catalyst demonstrates controlled H₂O₂ oxidation of allylic alcs., benzyl alcs., and aliphatic alcs. From a probe reaction, Pt catalytic activity to produce a carboxylic acid from the corresponding alc. improved depending on the temperature increasing from 40 to 90°C. The set of reaction conditions about the combination of temperature and flow rate as a simple trigger works sensitively to divide the formation of aldehydes and carboxylic acids without tuning by additives. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7Application of 873-76-7).

(4-Chlorophenyl)methanol (cas: 873-76-7) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters.

Anti-Markovnikov alkene oxidation by metal-oxo-mediated enzyme catalysis was written by Hammer, Stephan C.;Kubik, Grzegorz;Watkins, Ella;Huang, Shan;Minges, Hannah;Arnold, Frances H.. And the article was included in Science (Washington, DC, United States) in 2017.HPLC of Formula: 94022-96-5 This article mentions the following:

Catalytic anti-Markovnikov oxidation of alkene feedstocks could simplify synthetic routes to many important mols. and solve a long-standing challenge in chem. Here we report the engineering of a cytochrome P 450 enzyme by directed evolution to catalyze metal-oxo-mediated anti-Markovnikov oxidation of styrenes with high efficiency. The enzyme uses dioxygen as the terminal oxidant and achieves selectivity for anti-Markovnikov oxidation over the kinetically favored alkene epoxidation by trapping high-energy intermediates and catalyzing an oxo transfer, including an enantioselective 1,2-hydride migration. The anti-Markovnikov oxygenase can be combined with other catalysts in synthetic metabolic pathways to access a variety of challenging anti-Markovnikov functionalization reactions. In the experiment, the researchers used many compounds, for example, 2-(Trifluoromethyl)phenethyl alcohol (cas: 94022-96-5HPLC of Formula: 94022-96-5).

2-(Trifluoromethyl)phenethyl alcohol (cas: 94022-96-5) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.HPLC of Formula: 94022-96-5

Palladium-Mediated C_γ-H Functionalization of Alicyclic Amines was written by Aguilera, Ellen Y.;Sanford, Melanie S.. And the article was included in Angewandte Chemie, International Edition in 2021.Category: alcohols-buliding-blocks This article mentions the following:

This paper describes a new method for the transannular functionalization of the γ-C-H bonds in alicyclic amines to install C(sp³)-halogen, oxygen, nitrogen, boron, and sulfur bonds. The key challenge for this transformation is controlling the relative rate of C_γ-H vs. C_α-H functionalization. We demonstrate that this selectivity can be achieved by pre-complexation of the substrate with Pd prior to the addition of oxidant. This approach enables the use of diverse oxidants that ultimately install various heteroatom functional groups at the γ-position with high site- and diastereoselectivity. In the experiment, the researchers used many compounds, for example, 2,3,4,5-Tetrahydro-1H-1,5-methanobenzo[d]azepine hydrochloride (cas: 230615-52-8Category: alcohols-buliding-blocks).

2,3,4,5-Tetrahydro-1H-1,5-methanobenzo[d]azepine hydrochloride (cas: 230615-52-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Category: alcohols-buliding-blocks

An amino acid ester of menthol elicits defense responses in plants was written by Tsuzuki, Chisato;Hachisu, Masakazu;Iwabe, Rihoko;Nakayama, Yuna;Nonaga, Yoko;Sukegawa, Satoru;Horito, Shigeomi;Arimura, Gen-ichiro. And the article was included in Plant Molecular Biology in 2022.Related Products of 2216-51-5 This article mentions the following:

Terpenoids, including menthol, exhibit potent abilities as plant defense potentiators in agriculture and horticulture. In the current study, we developed new terpene derivatives that consisted of menthol and various amino acids and that were expected to act as powerful plant defense potentiators. We used 6 amino acids possessing low-reactive sidechains to synthesize an array of amino acid ester of menthol (ment-aa) compounds Transcript levels of two defense genes (pathogenesis-related protein 1 [PR1] and trypsin inhibitor [TI]) were evaluated in leaves of soybean plants 24 h after application of aquatic solution of menthol or menthol-aa, and revealed that the valine menthyl ester (ment-Val) alone elevated the transcript level of defense genes, and it did so only at the low dose of 1μM, not at higher or lower doses tested. Moreover, it appeared that histone acetylation was involved in this effect. Application of ment-Val enabled soybean plants to sustain the increased transcript levels in their leaves for up to 3 days. Moreover, when ment-Val was addnl. applied at day 4, at which time the transcript level had declined to the basal level, the transcript level was re-elevated, indicating the possibility that ment-Val could be repeatedly used to sustain pest control. Ment-Val was found to be chem. stable and effective for defense of several crop species. Collectively, these data show that terpenoid conjugates are useful for pest control instead of or in addition to pesticides. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Related Products of 2216-51-5).

(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom.
