A QSAR study of Overton’s tadpole data was written by Lipnick, Robert L.. And the article was included in Progress in Clinical and Biological Research in 1989.Computed Properties of C10H22O3 This article mentions the following:

Previously published data (Overton, E., 1901) on the narcotic and toxic effects of a number of organic compounds in Rana temporaria tadpoles were evaluated for structure-activity relationships. 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. 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.Computed Properties of C10H22O3

Small-dipole-molecule-containing electrolytes for high-voltage aqueous rechargeable batteries was written by Huang, Zhaodong;Wang, Tairan;Li, Xinliang;Cui, Huilin;Liang, Guojin;Yang, Qi;Chen, Ze;Chen, Ao;Guo, Ying;Fan, Jun;Zhi, Chunyi. And the article was included in Advanced Materials (Weinheim, Germany) in 2022.Electric Literature of C4H10O4 This article mentions the following:

High-voltage aqueous rechargeable batteries are promising competitors for next-generation energy storage systems with safety and high specific energy, but they are limited by the absence of low-cost aqueous electrolytes with a wide electrochem. stability window (ESW). The decomposition of aqueous electrolytes is mainly facilitated by the hydrogen bond network between water mols. and the water mols. in the solvation sheath. Here, three types of small dipole mols. (small mols. containing a dipole; glycerol (Gly), erythritol (Et), and acrylamide (AM)) are reported to develop aqueous electrolytes with high safety and wide ESW (over 2.5 V) for aqueous lithium-, sodium-, and zinc-ion batteries, resp. The solvation-sheath structures are explored by ab initio mol. dynamics (MD) simulations, demonstrating that three types of dipole mols. deplete the water mols. in the solvation sheath of the charge carrier and break the hydrogen bond network between the water mols., thus effectively expanding the ESW. A battery constructed from lithium titanate and lithium manganate in Gly-containing electrolyte exhibits an output voltage of 2.45 V and retains a specific capacity of 119.6 mAh g-1 after 400 cycles. This work provides another strategy for exploiting low-cost high-voltage electrolytes for aqueous energy-storage systems. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Electric Literature of C4H10O4).

(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. 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.Electric Literature of C4H10O4

Complete chiral induction from enantiopure 1,2-diamines to benzophenone-based achiral bisphosphane ligands in Noyori-type Ru^II catalysts was written by Jing, Qing;Sandoval, Christian A.;Wang, Zheng;Ding, Kuiling. And the article was included in European Journal of Organic Chemistry in 2006.Related Products of 171032-87-4 This article mentions the following:

The design and synthesis are reported of a novel class of Ru^II catalysts (R,R)-I⁺Cl^– (Ar = Ph, R = H, 5-t-Bu, 4-t-Bu; Ar = 3,5-Me₂C₆H₃, R = H) composed of achiral benzophenone-based bisphosphine ligands and enantiopure 1,2-diamines for the asym. hydrogenation of aryl ketones. The developed catalysts show excellent enantioselectivities (up to 97% ee) and activities (up to S/C = 10,000) in the hydrogenation of a variety of aromatic ketones. Complete chiral induction from the enantiopure 1,2-diamine to the achiral bisphosphine ligand was observed The coordination of the C:O moiety in I to the cationic Ru^II center is considered to be of key importance in providing a higher thermodn. and kinetic rotation barrier for the flexible bisphosphine ligand, resulting in the preferential formation of only one diastereomer, and thus explaining the high enantioselectivity of the catalyst.

Here a palladium-catalyzed oxidation method for converting alkylarenes into the aromatic ketones or benzaldehydes ArC(O)R¹ [Ar = Ph, 4-MeC₆H₄, 4-HOC₆H₄, etc.; R¹ = H, Ph, 4-ClC₆H₄, etc.] with water as the only oxygen donor was reported. This C-H bond oxidation functionalization did not require other oxidants and hydrogen acceptors, and H₂ was the only byproduct. The oxygen atom introduced into the products was confirmed to be from water by the MS anal. on the product of the ¹⁸O-labeled water reaction. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7COA of Formula: C7H7ClO).

(4-Chlorophenyl)methanol (cas: 873-76-7) 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. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.COA of Formula: C7H7ClO

And the article was included in Industrial Crops and Products in 2022.Application of 499-75-2 This article mentions the following:

Zataria multiflora Boiss.(ZM) is an aromatic herb that is used in various industries, especially in pharmaceuticals and food. However, the inducer effect of elicitors on ZM, with the aim of increasing the bioactive compounds production, is understudied. This study analyzes the influence of a biotic (chitin) and abiotic (copper nanoparticle) elicitor on ZM under in vitro and greenhouse conditions. In the first step, having established in Murashige and Skoog medium (MS) based on the node culture method, the explants transferred to media with different blended to survey the improvements in growth. The modified MS having faster growth and propagation in ZMs was chosen. In the second step, when explants were grown and rooted enough, they were transmitted to the media of elicitors, including four copper oxide nanoparticle concentrations (0, 25, 50, & 100 mg L-1) and four chitin concentrations (0, 50, 100 & 200 mg L-1) at two exposure times (5 and 10 days) to measure biochem. attributes. The anal. showed that the highest contents of the total phenolic (6.44 mg g-1 FW), anthocyanins (39.59 mg g-1 FW), flavonols (0.76 mg g-1 FW), and flavonoids (0.97 mg g-1 FW) compounds were observed in the elicited ZMs. In addition, the components of secondary metabolites were identified by gas chromatog.-mass spectrometry (GC-MS) anal. It was revealed that the highest amount of thymol and carvacrol, as the main compositions of ZM, was in the copper oxide nanoparticle (2.51% and 38.03% resp.), control (2.34% and 28.51% resp.), and chitin (1.92% and 9.84% resp.) ZMs in turn. The present research indicates that choosing an appropriate elicitor, concentration, and exposure time for augmenting the production of bioactive compounds in each plant species is consequential so as to provide the possibility of utilizing in industry. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Application of 499-75-2).

5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. 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.Application of 499-75-2

The aim of the present study was to prepare the thyme essential oil (TEO) nano-emulsion (5, 10, 15 and 20%) incorporated edible composite films using tamarind starch (TS), whey protein concentrate (WPC) at selected proportions. Impact on phys., mech. and barrier properties of the composite films was investigated. The average particle size of nano-emulsions was found to be 18.88 nm and PDI value of 0.304. Carvacrol (41.29%), thymol (26.31%) and p-cymene (10.63%) were the main chem. compounds determined using GC-MS study. With the incorporation of WPC and TEO into film, water gain, and solubility of the films improved significantly to enhance the shelf life of tomato till 14 days. Synergistic effect of WPC and TEO significantly improved the tensile strength and elongation properties of the films. The inhibition zone was found to be (53.33 ± 2.60) mm for S.aureus and (39.86 ± 3.12) mm for E.coli at 20% TEO. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Related Products of 499-75-2).

5-Isopropyl-2-methylphenol (cas: 499-75-2) 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. 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.Related Products of 499-75-2

And the article was included in Brazilian Journal of Microbiology in 2022.COA of Formula: C8H16O This article mentions the following:

The aim of this study was to evaluate the biosynthesis of flavor compounds from rice bran by fermentation facilitated by Kluyveromyces marxianus and Debaryomyces hansenii. The growth of both yeasts was assessed by specific growth rates and doubling time. The biosynthesis of flavor compounds was evaluated by gas chromatog.-olfactometry (GC-O), gas chromatog.-mass spectrometry (GC-MS), and Spectrum sensory anal. The specific growth rate (μ) and doubling time (td) of K. marxianus was calculated as 0.16/h and 4.21h, resp., whereas that of D. hansenii was determined as 0.13/h and 5.33h, resp. K. marxianus and D. hansenii produced significant levels of higher alcs. and acetate esters from rice bran. Results showed that K. marxianus can produce 827.27μg/kg of isoamyl alc., 169.77μg/kg of Ph Et alc., and 216.08μg/kg of Ph Et acetate after 24-h batch fermentation A significant amount of isovaleric acid was also synthesized by K. marxianus (4013μg/kg) after the batch fermentation of 96 h. 415.64μg/kg of isoamyl alc. and 135.77μg/kg of Ph Et acetate was determined in rice bran fermented by D. hansenii after 24-h fermentation Fermented cereals and rose were the characteristic flavor descriptors of the fermented rice bran samples. Rose flavor in fermented rice bran samples was found to be associated with Ph Et alc., Ph Et acetate, isoamyl acetate, and guaiacol. Thus, the findings of this study demonstrate that the valorization of rice bran can be achieved with the production of natural flavor compounds by yeast metabolism In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4COA of Formula: C8H16O).

Cyanamide as a Highly Efficient Organocatalyst for the Glycolysis Recycling of PET was written by Wang, Zishuai;Jin, Yu;Wang, Yaoqiang;Tang, Zequn;Wang, Shaojie;Xiao, Gang;Su, Haijia. And the article was included in ACS Sustainable Chemistry & Engineering in 2022.Synthetic Route of C4H10O3 This article mentions the following:

Due to the antibiodegradable properties, numerous plastics have been accumulated in the ecosystem and aggravate ecol. pollution. Poly (ethylene terephthalate) (PET) is among the most used plastics. Glycolysis of PET is a useful approach to solve the waste PET pollution and obtain bis(2-hydroxyethyl) terephthalate (BHET). In this paper, waste PET was efficiently depolymerized through glycolysis catalyzed by cyanamide. In particular, compared with the previously reported catalyst, cyanamide is more readily available and can be used directly in catalysis without a complex preparation process. Under optimal conditions, PET was completely depolymerized with up to nearly 100% BHET yield. Even at a temperature as low as 150°C, a good BHET yield can be obtained. The application potential of this glycolysis procedure was demonstrated by its excellent performance in the glycolysis of various real PET wastes like transparent and opaque PET samples and polyester foam and by the high quality of the obtained BHET products. The mechanism was studied by ¹H NMR anal., and DFT calculations showed that the higher activity of cyanamide than its trimer, melamine, is due to the stronger hydrogen bonds formed between cyanamide and PET or ethylene glycol. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Synthetic Route of C4H10O3).

2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group.
