RAFT grafting polymerization of styrene on the surface of SiO₂ was written by Li, De-ling;Wang, Wei;Li, Ping;Wang, Dong-chao. And the article was included in Gongneng Gaofenzi Xuebao in 2012.Related Products of 27249-90-7 This article mentions the following:

Double bonds were immobilized onto nano-SiO₂ via hydrolyzing alkoxysilane moiety of γ-methacryl trimethoxysilane for condensation with hydroxide groups from nano-SiO₂. RAFT grafting polymerization of styrene from nano-SiO₂ was carried out from the immobilized double bonds, in which azobisisobutyronitrile was used as initiator, 2-cyanoprop-2-yl dithiobenzoate, benzyl dithiobenzoate, benzyl dithiopivalate, 1,2,4-triazolyl-1-carbodithioic acid benzyl ester were used as RAFT agent, resp. Results showed that RAFT grafting polymerization rate of styrene from SiO₂ was decided by Z group of RAFT agent. Grafting polymerization of styrene from SiO₂ mediated by benzyl dithiopivalate exhibited the highest grafting polymerization rate. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Related Products of 27249-90-7).

Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Comprehensive insights into the interactions of dicyclohexyl phthalate and its metabolite to human serum albumin was written by Lv, Xiaolan;Jiang, Zheng;Zeng, Guofang;Zhao, Sujuan;Li, Na;Chen, Fengping;Huang, Xiaojian;Yao, Jia;Tuo, Xun. And the article was included in Food and Chemical Toxicology in 2021.Application In Synthesis of Dicyclohexyl phthalate This article mentions the following:

Phthalate esters (PAEs) are a type of persistent organic pollutants and have received widespread concerns due to their adverse effects on human health. Dicyclohexyl phthalate (DCHP) and its metabolite monocyclohexyl phthalate (MCHP) were selected to explore the mechanism for interaction of PAEs with human serum albumin (HSA) through mol. docking and several spectroscopic techniques. The results showed that DCHP/MCHP can spontaneously occupy site I to form a binary complex with HSA, and DCHP exhibited higher binding affinity to HSA than MCHP. At 298 K, the binding constants (K_b) of DCHP and MCHP to HSA were 24.82 x 10⁴ and 1.04 x 10⁴ M^-1, resp. Hydrogen bonds and van der Waals forces were the major driving forces in DCHP/MCHP-HSA complex. The presence of DCHP/MCHP induced the secondary structure changes in HSA, and the pi electrons of the benzene ring skeleton of DCHP/MCHP played a key role in this binding processes. Exposure of DCHP/MCHP to TM4 cells revealed that interactions between PAEs and serum albumin can affect their cytotoxicity; DCHP showed higher toxicity than MCHP. The binding affinity of PAEs with HSA may be a valuable parameter for rapid assessment of their toxicity to organisms. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Application In Synthesis of Dicyclohexyl phthalate).

Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Application In Synthesis of Dicyclohexyl phthalate

2,3-Carbamate mannosamine glycosyl donors in glycosylation reactions of diacetone-D-glucose. An experimental and theoretical study was written by Morelli, Laura;Legnani, Laura;Ronchi, Silvia;Confalonieri, Laura;Imperio, Daniela;Toma, Lucio;Compostella, Federica. And the article was included in Carbohydrate Research in 2021.SDS of cas: 6730-10-5 This article mentions the following:

The role of the cyclic 2,3-N,O-carbamate protecting group in directing the selectivity of mannosylation reactions of diacetone-D-glucose, promoted by BSP/Tf₂O via α-triflate intermediates, has been investigated through a combined computational and exptl. approach. DFT calculations were used to locate the transition states leading to the α or β anomers. These data indicate the preferential formation of the β-adduct with mannosyl donors either equipped with the 4,6-O-benzylidene protection or without it. The synthetic results confirmed this preference, showing in both cases an α/β selectivity of 4:6. This highlights a role for the 2,3-N,O-carbamate in sharp contrast with what described in the case of 2,3-O-carbonate mannosyl donors. In the experiment, the researchers used many compounds, for example, (2S,3S,4R,5S,6R)-3-Acetamido-6-(acetoxymethyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate (cas: 6730-10-5SDS of cas: 6730-10-5).

(2S,3S,4R,5S,6R)-3-Acetamido-6-(acetoxymethyl)tetrahydro-2H-pyran-2,4,5-triyl triacetate (cas: 6730-10-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 6730-10-5

Machine learning-based prediction of toxicity of organic compounds towards fathead minnow was written by Chen, Xingmei;Dang, Limin;Yang, Hai;Huang, Xianwei;Yu, Xinliang. And the article was included in RSC Advances in 2020.Application In Synthesis of Ethyl 2-hydroxybenzoate This article mentions the following:

Predicting the acute toxicity of a large dataset of diverse chems. against fathead minnows (Pimephales promelas) is challenging. In this paper, 963 organic compounds with acute toxicity towards fathead minnows were split into a training set (482 compounds) and a test set (481 compounds) with an approx. ratio of 1 : 1. Only six mol. descriptors were used to establish the quant. structure-activity/toxicity relationship (QSAR/QSTR) model for 96 h pLC₅₀ through a support vector machine (SVM) along with genetic algorithm. The optimal SVM model (R² = 0.756) was verified using both internal (leave-one-out cross-validation) and external validations. The validation results (q_int² = 0.699 and q_ext² = 0.744) were satisfactory in predicting acute toxicity in fathead minnows compared with other models reported in the literature, although our SVM model has only six mol. descriptors and a large data set for the test set consisting of 481 compounds In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxybenzoate (cas: 118-61-6Application In Synthesis of Ethyl 2-hydroxybenzoate).
