Shape memory polymer foams synthesized using glycerol and hexanetriol for enhanced degradation resistance was written by Hasan, Sayyeda Marziya;Fletcher, Grace K.;Monroe, Mary Beth Browning;Wierzbicki, Mark A.;Nash, Landon D.;Maitland, Duncan J.. And the article was included in Polymers (Basel, Switzerland) in 2020.SDS of cas: 115-84-4 The following contents are mentioned in the article:

Shape memory polymer foams have been used in a wide range of medical applications, including, but not limited to, vessel occlusion and aneurysm treatment. This unique polymer system has been proven to shape-fill a void, which makes it useful for occlusion applications. While the shape memory polymer foam has superior performance and healing outcomes compared to its leading competitors, some device applications may benefit from longer material degradation times, or degradation-resistant formulations with increased fibrous encapsulation. In this study, biostable shape memory polymer foams were synthesized, and their phys. and chem. properties were characterized as an initial evaluation of feasibility for vascular occlusion applications. After characterizing their shape memory behavior in an aqueous environment, degradation of this polymer system was studied in vitro using accelerated oxidative and hydrolytic solutions Results indicated that the foams did not lose mass under oxidative or hydrolytic conditions, and they maintained high shape recovery in aqueous in vitro models. These degradation-resistant systems have potential for use in vascular occlusion and other wound healing applications that benefit from permanent, space-filling shape memory behavior. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4SDS of cas: 115-84-4).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. 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.SDS of cas: 115-84-4

Production and Characterization of Odorless Antioxidative Hydrolyzed Collagen from Seabass (Lates calcarifer) Skin Without Descaling was written by Benjakul, Soottawat;Karnjanapratum, Supatra;Visessanguan, Wonnop. And the article was included in Waste and Biomass Valorization in 2018.Recommanded Product: 106-21-8 The following contents are mentioned in the article:

Odorless hydrolyzed collagen (HC) powder from fish skin with antioxidative activity has gained increasing demand. This investigation aimed to compare the impacts of different hydrolysis processes of seabass skin without descaling as well as spray-drying conditions on characteristics and antioxidative activities of resulting HC. For one-step hydrolysis, 3% papain at 40 °C for 3 h (P) or 2% alcalase at 50 °C for 2 h (A) were used. Two-step hydrolysis, conducted as stepwise process using the combination of both processes, included P + A and A + P. P + A process rendered the HC with higher yield, hydroxyproline recovery, α-amino group content and antioxidative activities, compared to one-step process and A + P process (P < 0.05). HC powder obtained from spray-drying with inlet temperature of 200 °C showed the lower abundance of odorous compounds, compared with that using 150 °C. Nevertheless, no differences in antioxidative activity were obtained between both HCs (P > 0.05). The odorless antioxidative HC powder possessed high pH and thermal stability. Therefore, the combination of appropriate processes including hydrolysis and drying could yield the odorless antioxidative HC powder, which could widen the applications in food or pharmaceutical products. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Recommanded Product: 106-21-8).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) 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.Recommanded Product: 106-21-8

Corrosion performance of polyurethane hybrid coatings with encapsulated inhibitor was written by Alrashed, Maher M.;Jana, Sadhan;Soucek, Mark D.. And the article was included in Progress in Organic Coatings in 2019.Electric Literature of C9H20O2 The following contents are mentioned in the article:

Direct incorporation of inhibitor mols. in hybrid coatings results in premature deterioration of coatings performance. The inhibitor mols. interfere with curing of the organic coating and cause delamination due to fast leaching. This challenge is overcome in this work by encapsulating an effective organic inhibitor, 2-mercaptobenzothiazole (MBT), in polylactic acid (PLA) nanoparticles produced via nanopptn. method for corrosion protection of 2024-T3 aluminum alloy. The nanoparticles are designed as function of polylactic acid concentration, solvent/antisolvent volume ratio, and the PLA/MBT mass ratio. Nanoparticle size distribution, inhibitor loading percentage, and encapsulation efficiency are studied. The PLA nanoparticles with encapsulated MBT are incorporated in a polyurethane/polysiloxane hybrid coating and its properties are evaluated using impact resistance, pull-off strength, cross-hatch adhesion, pencil and pendulum hardness, and solvent resistance. The corrosion performance of the hybrid coatings is investigated by electrochem. impedance spectroscope (EIS) and potentiostatic polarization. The polyurethane/polysiloxane hybrid coating shows a 200-fold increase in corrosion induction time due to incorporation of MBT-impregnated PLA nanoparticles. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Electric Literature of C9H20O2).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) 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.Electric Literature of C9H20O2

Biological effects of combustion-derived particles from different biomass sources on human bronchial epithelial cells was written by Marchetti, Sara;Mollerup, Steen;Gutzkow, Kristine Bjerve;Rizzi, Cristiana;Skuland, Tonje;Refsnes, Magne;Colombo, Anita;Oevrevik, Johan;Mantecca, Paride;Holme, Joern Andreas. And the article was included in Toxicology In Vitro in 2021.Product Details of 115-84-4 The following contents are mentioned in the article:

Combustion-derived particles (CDPs), in particular from traffic, are regarded as a central contributor for adverse health effects linked to air pollution. Recently, also biomass burning has been recognized as an important source for CDPs. Here, the effects of CDPs (PM10) originating from burning of pellet, charcoal and wood on key processes associated to lung carcinogenesis were explored. Human bronchial epithelial cells (HBEC3-KT) were exposed to 2.5μg/cm2 of CDPs for 24 h and biol. effects were examined in terms of cytotoxicity, inflammation, epithelial to mesenchymal transition (EMT)-related effects, DNA damage and genotoxicity. Reduced cell migration, inflammation and modulation of various PM-associated genes were observed mainly after exposure to wood and pellet. In contrast, only particles from pellet burning induced alteration in cell proliferation and DNA damage, which resulted in cell cycle alterations. Charcoal instead, appeared in general less effective in inducing pro-carcinogenic effects. These results illustrate differences in the toxicol. profile due to the CDPs source. The different chem. compounds adsorbed on CDPs seemed to be central for particle properties, leading to an activation of various cellular signaling pathways involved in early steps of cancer progression. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Product Details of 115-84-4).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) 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. 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.Product Details of 115-84-4

Equilibrium of boron extraction with 2-butyl-2-ethyl-1,3-propanediol and 2-ethylhexanol in butyl acetate was written by Kwon, Taeok;Hirata, Makoto;Hano, Tadashi;Yamagishi, Toshio. And the article was included in Separation Science and Technology in 2005.Electric Literature of C9H20O2 The following contents are mentioned in the article:

Boron extraction with 2-butyl-2-ethyl-1,3-propanediol (BEPD) and 2-ethylhexanol (EHA) in Bu acetate (BA) was carried out at various boron and extractants concentrations The distribution ratio of boron was constant for all boron concentrations when EHA was used as the extractant, and it increased with EHA concentration When high concentrations of BEPD were used as the extractant, the distribution ratio of boron was almost the same for all boron concentrations The distribution ratio of boron increased with BEPD concentrations An increase in the initial concentration of boron in the aqueous phase severely decreased the boron distribution ratio at low initial concentrations of BEPD in the organic phase. This was caused by the dissolution of BEPD into aqueous solution The loss of BEPD into the aqueous phase became severe as the concentration of boron in the aqueous phase increased. The loss of EHA was insignificant for all boron concentrations The distribution ratio of boron was plotted with a function of the equilibrium concentrations of the extractants. The plots showed a linear relation indicating that boron extraction resulted from the same mechanism in all the extraction systems examined in the present study. Distribution equations for all the extraction systems were derived. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Electric Literature of C9H20O2).

2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) 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. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Electric Literature of C9H20O2

Synthesis of “Nereid”, new phenol-free detergent to replace triton X-100 in virus inactivation was written by Farcet, Jean-Baptiste;Kindermann, Johanna;Karbiener, Michael;Scheinecker, Richard;Kostner, Otto;Kreil, Thomas R.. And the article was included in Journal of Medical Virology in 2021.SDS of cas: 106-21-8 The following contents are mentioned in the article:

In the 1980s, virus inactivation steps were implemented into the manufacturing of biopharmaceuticals in response to earlier unforeseen virus transmissions. The most effective inactivation process for lipid-enveloped viruses is the treatment by a combination of detergents, often including Triton X-100 (TX-100). Based on recent environmental concerns, the use of TX-100 in Europe will be ultimately banned, which forces the pharmaceutical industry, among others, to switch to an environmentally friendly alternative detergent with fully equivalent virus inactivation performance such as TX-100. In this study, a structure-activity relationship study was conducted that ultimately led to the synthesis of several new detergents. One of them, named “Nereid”, displayed inactivation activity fully equivalent to TX-100. The synthesis of this replacement candidate has been optimized to allow for the production of several kg of detergent at lab scale, to enable the required feasibility and comparison virus inactivation studies needed to support a potential future transition. The 3-step, chromatog.-free synthesis process described herein uses inexpensive starting materials, has a robust and simple work-up, and allows production in a standard organic laboratory to deliver batches of several hundred grams with >99% purity. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8SDS of cas: 106-21-8).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) 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. 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.SDS of cas: 106-21-8

Prediction of the Normal Boiling Points and Enthalpy of Vaporizations of Alcohols and Phenols Using Topological Indices was written by Arjmand, F.;Shafiei, F.. And the article was included in Journal of Structural Chemistry in 2018.Related Products of 106-21-8 The following contents are mentioned in the article:

Establishing quant. correlations between various mol. properties and chem. structures is of great technol. importance for environmental and medical aspects. These approaches are referred to as Quant. Structure-Property Relationships (QSPR), which relate the physico-chem. or thermodn. properties of compounds to their structures. The main goal of QSPR studies is to find a math. relationship between the property of interest and a number of mol. descriptors derived from the structure of the mol. The current study presents the relationship between the Randic’ (¹χ), Balaban (J),Wiener polarity (W_p), Hyper Wiener (WW), Szeged (Sz), Harary (H) and Wiener (W) indexes to the normal b.ps. (T_bp, K) and the standard enthalpies of vaporization (ΔH⁰_vap, kJ/mol^-1) of 227 alcs. and phenols. The multiple linear regression (MLR) and backward methods were employed to give the QSPR models. After MLR anal., we studied the validation of linearity between the mol. descriptors in the best models for used properties. The results have shown that three descriptors (W, ¹χ, J) could be efficiently used for estimating the normal b.ps., and two descriptors (¹χ, J) could be used for modeling and predicting the standard enthalpies of vaporization of considered compounds This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Related Products of 106-21-8).

Effect of gem 2,2′-disubstitution and base in the formation of spiro- and ansa-1,3-propandioxy derivatives of cyclotriphosphazenes was written by Uslu, Aylin;Coles, Simon J.;Davies, David B.;Esen, Muekremin;Hursthouse, Michael B.;Kilic, Adem. And the article was included in Inorganica Chimica Acta in 2010.Formula: C9H20O2 The following contents are mentioned in the article:

The gem-dialkyl effect was studied in the reactions of cyclotriphosphazene, N₃P₃Cl₆ 1, with various 2,2′-derivatives of 1,3-propandiol, CXY(CH₂OH)₂, in either THF or DCM to form spiro (6-membered) and ansa (8-membered ring) derivatives The reactions were made with a number of sym.-substituted (X = Y, Me, Et, Bu and a malonate ester) and unsym.-substituted (X ≠ Y, Me/H, Ph/H, Me/Pr, Et/Bu and Br/NO₂) 1,3-propandiols. The products were analyzed by ¹H and ³¹P NMR spectroscopy and some of the spiro and ansa derivatives were also characterized by x-ray crystallog. Reactions of 1 with unsym.-substituted 1,3-propandiols gave two structural isomers of ansa-substituted compounds, both isomers (endo and exo) were structurally-characterized by x-ray crystallog. for the Et/Bu derivative The regioselectivity of the reaction is changed when the base is changed. The relative proportions of spiro and ansa compounds formed under different reaction conditions were quantified by ³¹P NMR measurements of the reaction mixtures The results were rationalized mainly in terms of the electronic effect of the substituents, whereas the steric effect has a secondary role in the formation of both spiro and ansa compounds This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Formula: C9H20O2).
