Boronate ester cross-linked hydrogels have emerged as promising injectable scaffolds for biomedical applications given their rapid self-healing ability. For a rational design of such networks, all variables influencing their dynamic rheol. properties, especially the boronic acid and the diol-containing mol. selected as mol. crosslinkers have to be carefully considered. Herein, by tailoring the structure of benzoxaborole (BOR), self-crosslinking hydrogels based on hyaluronic acid (HA) modified with BOR derivatives are obtained for the first time through the direct BOR-HA diol complexation at physiol. pH. Among the different HA-BOR conjugates investigated, those prepared from 6-amino-7-fluoro-3,3-dimethyl benzoxaborole (HA-DMF6ABOR) and 7-amino-3,3-dimethyl benzoxaborole (HA-DM7ABOR) show unprecedented self-crosslinking properties, leading to the formation of self-healing hydrogels with extremely slow dynamics. These networks also exhibit remarkable pH- and glucose-responsive behaviors. These properties are related to the peculiar structure of these two BOR moieties, having as the common feature, a gem-di-Me group in the oxaborole ring and an ortho-substituent in the Ph ring. Mol. dynamic simulations are used to provide insight in the role of these substituents in the outstanding capability of DMF6ABOR and DM7ABOR to crosslink HA. They show that BOR complexation induces changes in conformation of HA favoring formation of a highly entangled 3D network. This study involved multiple reactions and reactants, such as 7-Fluoro-1,3-dihydro-2,1-benzoxaborol-1-ol (cas: 174671-93-3Recommanded Product: 7-Fluoro-1,3-dihydro-2,1-benzoxaborol-1-ol).

7-Fluoro-1,3-dihydro-2,1-benzoxaborol-1-ol (cas: 174671-93-3) 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: 7-Fluoro-1,3-dihydro-2,1-benzoxaborol-1-ol

Tandem Synthesis of Ultra-High Molecular Weight Drag Reducing Poly-α-Olefins for Low-Temperature Pipeline Transportation was written by Nifant’ev, Ilya E.;Tavtorkin, Alexander N.;Vinogradov, Alexey A.;Korchagina, Sofia A.;Chinova, Maria S.;Borisov, Roman S.;Artem’ev, Grigory A.;Ivchenko, Pavel V.. And the article was included in Polymers (Basel, Switzerland) in 2021.Product Details of 115-84-4 The following contents are mentioned in the article:

Ultra-high mol. weight poly-α-olefins are widely used as drag reducing agents (DRAs) for pipeline transportation of oil and refined petroleum products. The synthesis of polyolefin DRAs is based on low-temperature Ziegler-Natta (ZN) polymerization of higher α-olefins. 1-Hexene based DRAs, the most effective at room temperature, typically lose DR activity at low temperatures The use of 1-hexene copolymers with C8-C12 linear α-olefins appears to offer a solution to the problem of low-temperature drag reducing. The present work aims to develop two-stage synthesis of polyolefin DRAs that is based on selective oligomerization of ethylene in the presence of efficient chromium/aminodiphosphine catalysts (Cr-PNP), followed by polymerization of the olefin mixtures, formed at oligomerization stage, using efficient titanium-magnesium ZN catalyst. We have shown that oligomerization of ethylene in α-olefin reaction media proceeds faster than in saturated hydrocarbons, providing the formation of 1-hexene, 1-octene, and branched C10 and C12 olefins; the composition and the ratio of the reaction products depended on the nature of PNP ligand. Oligomerizates were used in ZN polymerization ‘as is’, without addnl. treatment. We assume that faster solubility and more efficient solvation of the polyolefins, prepared using ‘tandem’ ethylene-based process, represent an advantage of these type polymers over conventional poly(1-hexene) and linear α-olefin-based polymers when used as ‘winter’ DRAs.

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.Product Details of 115-84-4

Characterisation of taste-active compositions, umami attributes and aroma compounds in Chinese shrimp was written by Chen, Lihua;Zeng, Wenhua;Rong, Yuzhi;Lou, Bao. And the article was included in International Journal of Food Science and Technology in 2021.Category: alcohols-buliding-blocks The following contents are mentioned in the article:

Chinese shrimp is one of the most important aquatic resource in China due to its unique flavor and high nutritional value. In this study, the taste-active components including free amino acids (FAAs), 5′-nucleotides, organic acids, inorganic ions, trimethylamine oxide (TMAO) and betaine were analyzed. The synergistic effect between amino acids and 5′-nucleotides was determined by partial least squares (PLS) anal. The taste activity value (TAV) and equivalent umami concentration (EUC) were calculated to analyze the major taste-active components and umami attributes. Then, the aroma compounds were extracted by simultaneous distillation extraction (SDE), head-space solid-phase microextraction (HS-SPME) and supercritical fluid extraction (SFE) methods, resp., and identified by gas chromatog.-mass spectrometry (GC-MS). Arginine (Arg), glycine (Gly), GMP (5′-GMP), inosine-5′-monophosphate (5′-IMP), de-nosine-5′-monophosphate (5′;-AMP), succinic acid, lactic acid and inorganic ions with TAV higher than 1 contributed greatly to the taste. The umami intensity for 100 g of Chinese shrimp was equivalent to 4.58 g monosodium glutamate (MSG), indicating that Chinese shrimp had relatively high umami taste value. Ninety-seven volatile compounds including esters, alcs., acids, aldehydes, ketones, heterocycles, aromatics and alkanes were identified. This research might help consumers to understand the flavor compositions and promote the development of flavor products of Chinese shrimp.

Two novel low band gap donor-acceptor (D-A) copolymers, poly[9,10-bis(4-(dodecyloxy)phenyl)-2,6-anthracene-alt-5,5-(4′,7′-bis(2-thienyl)-2′,1′,3′-benzothiadiazole-N-5,6-(3,7-dimethyloctyl)dicarboxylic imide)] (PPADTBTDI-DMO) and poly[9,10-bis(4-(dodecyloxy)phenyl)-2,6-anthracene-alt-5,5-(4′,7′-bis(2-thienyl)-2′,1′,3′-benzothiadiazole-5,6-N-octyl-dicarboxylic imide)] (PPADTBTDI-8) were synthesized in the present work by copolymerising the bis-boronate ester of 9,10-phenylsubstituted anthracene flanked by thienyl groups as electron-donor units with benzothiadiazole dicarboxylic imide (BTDI) as electron-acceptor units. Both polymers were synthesized in good yields via Suzuki polymerization Two different solubilizing alkyl chains were anchored to the BTDI units in order to investigate the impact upon their solubilities, mol. weights, optical and electrochem. properties, structural properties and thermal stability of the resulting polymers. Both polymers have comparable mol. weights and have a low optical band gap (Eg) of 1.66 eV. The polymers have low-lying HOMO (HOMO) levels of about -5.5 eV as well as the similar LUMO (LUMO) energy levels of -3.56 eV. Thermogravimetric analyses (TGA) of PPADTBTDI-DMO and PPADTBTDI-8 did not prove instability with decomposition temperatures at 354 and 313°C, resp. Powder X-ray diffraction (XRD) studies have shown that both polymers have an amorphous nature in the solid state, which could be used as electrolytes in optoelectronic devices.

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

And the article was included in Chemosphere in 2015.Name: 2-Butyl-2-ethylpropane-1,3-diol The following contents are mentioned in the article:

An anal. method has been developed for the pressurized liquid extraction (PLE) of a wide range of semi-volatile organic compounds (SVOCs) from atm. particulate matter. Approx. 130 SVOCs from eight compound classes were selected as mol. markers of (1) agricultural activity (30 current and historic-use pesticides), (2) industrial activity (18 PCBs), (3) consumer products and building materials (16 PBDEs, 11 OPEs), and (4) motor vehicle exhaust (22 PAHs, 16 alkanes, 9 hopanes, 8 steranes). Currently, there is no anal. method validated for the extraction of all eight compound classes in a single automated technique. The extraction efficiencies of varying solvents and solvent combinations at high temperatures and pressures were examined Extracts were concentrated and analyzed by gas chromatog. coupled with mass spectrometry. The optimized PLE method utilized methylene chloride:acetone (2:1 volume/volume) at 100 °C with three (5 min) static cycles, flush volume of 80%, and a 100 s N₂ purge. Spike and recovery experiments (n = 7) provided average percent recoveries for pesticides, PCBs, PBDEs, OPEs, PAHs, alkanes, hopanes, and steranes of 88.8 ± 4.0%, 86.9 ± 2.6%, 83.8 ± 2.9%, 101 ± 6%, 90.3 ± 6.1%, 74.4 ± 8.8%, 104 ± 8%, and 86.5 ± 8.6%, resp.

Effect of pigmentation on polyurethane/polysiloxane hybrid coatings was written by Gao, Tongzhai;Maya-Visuet, Enrique;He, Zhouying;Castaneda-Lopez, Homero;Zvonkina, Irina J.;Soucek, Mark D.. And the article was included in Journal of Applied Polymer Science in 2016.Name: 2-Butyl-2-ethylpropane-1,3-diol The following contents are mentioned in the article:

Rutile TiO₂ was formulated into polyurethane/polysiloxane hybrid coatings in order to investigate the influence of pigmentation on the inorganic phase of the hybrid coatings. Two urethanes were prepared from the isocyanurate of hexane diisocyanate (HDI), alkoxysilane modified HDI, and tetra-Et orthosilicate (TEOS) oligomers, with oligoesters derived from either cyclohexane diacids (CHDA) and 2-butyl-2-ethyl-1,3-propanediol (BEPD) or adipic acid (AA), isophthalic acid (IPA), 1,6-hexanediol (HD), and trimethylol propane (TMP). The oligoesters were spectroscopically characterized using GPC, FT-IR, and NMR. Chem. interaction between the TiO₂ and the sol-gel precursor was investigated using solid-state ²⁹Si NMR and XPS. The morphol., mech., viscoelastic, thermal properties of the pigmented coatings are evaluated as a function of pigmentation volume concentration (PVC). Using AFM and SEM, the pigment was observed to be well dispersed in the polymer binder. The thermal stability, the tensile modulus, and strength of the coatings were enhanced with increasing PVC, whereas the pull-off adhesion and flexibility (elongation-at-break) were reduced with increasing PVC. Finally, the pigmented coatings were evaluated by electrochem. impedance spectroscopy (EIS) and the results showed that 10 wt % of the pigment improved the corrosion resistance of the entire coating system. © 2015 Wiley Periodicals, Inc.

Influence of salt of different origin on the microbiological characteristics, histamine generation and volatile profile of salted anchovies (Engraulis encrasicolus L.) was written by Alfonzo, Antonio;Gaglio, Raimondo;Francesca, Nicola;Barbera, Marcella;Saiano, Filippo;Santulli, Andrea;Matraxia, Michele;Rallo, Francesco;Moschetti, Giancarlo. And the article was included in Food Control in 2018.Recommanded Product: 106-21-8 The following contents are mentioned in the article:

The effect of six salts of different geog. areas on the quality of salted anchovies was evaluated. The crude salts were chem. characterized by determination of inorganic and volatile organic compounds (VOCs). Salted anchovies, corresponding to six exptl. trials, were subjected to microbiol., chem. (including histamine content) and sensory anal. during the entire period of ripening (150 days). The salts were characterized by marked differences in terms of major cations and trace element amounts Among the 27 VOCs detected, octadecane was the most abundant compound and the main differences of the salts were registered for alkanes and alcs. During maturation, significant microbiol. differences between the salts were found for the levels of total aerobic mesophilic microorganisms, lactic acid bacteria, Staphylococcaceae and Enterobacteriaceae counts. All salted anchovies contained histamine below the thresholds allowed by current regulations, but statistical differences were registered for the concentrations of the different trials. Consistent differences were also revealed for their sensory profiles, in particular concerning odor and taste and overall acceptability. Several differences were also detected for dryness, brown color, putrid odor, rancid and raw blood taste sensory attributes. Especially the differences in the composition (chem. and VOC’s) of the raw salts used for the production of salted anchovies has a significant effect on the sensory characteristics of the final product.

The role of halogens in the catalyst transfer polycondensation for π-conjugated polymers was written by Ye, Shuyang;Foster, Scott M.;Pollit, Adam A.;Cheng, Susan;Seferos, Dwight S.. And the article was included in Chemical Science in 2019.Category: alcohols-buliding-blocks The following contents are mentioned in the article:

Catalyst transfer polycondensation is the only method to prepare π-conjugated polymers in a chain-growth manner, yet several aspects that underlie this polymerization are not fully understood. Here, we investigate the nickel-catalyzed polymerization mechanisms of a series of thiophene monomers bearing different halogen functionalities (Cl, Br, I). We have discovered the significant role that halogens and magnesium salts play in this polymerization More specifically, the catalyst resting state changes depending on the type of halogenated monomer. For chlorinated monomers a mixture of Ni(II)-dithienyl and dissociated Ni(phosphine) complexes are the resting states, which results in uncontrolled polymerization For brominated monomers, a Ni(II)-dithienyl complex is the resting state, which leads to controlled polymerization For iodinated monomers, a Ni(II)-thienyl iodide complex is the resting state, and notable inhibition by magnesium salt byproducts is observed The catalyst resting state changes to a Ni(II)-dithienyl complex when a turbo Grignard reagent (i-PrMgCl.LiCl) is used. These findings are used to guide the design of a new monomer, 2-bromo-3-(2-ethylhexyl)-5-iodotellurophene, which enables the first controlled polymerization of a tellurophene monomer containing a sterically encumbered 2-ethylhexyl side chain. These insights are crucial for deepening the mechanistic understanding of Kumada cross coupling reactions and the controlled synthesis of π-conjugated polymers.
