Zhang, Yue-Fei;Tang, Jian;Li, Tao;Liu, Yun;Li, Yan research published 《 UV-mediated atom transfer radical polymerization of acrolein》, the research content is summarized as follows. In this paper, the polymerization of acrolein (A) via UV-mediated atom transfer radical polymerization (ATRP) is reported. The optimization of the exptl. conditions of the polymerization is investigated, and it shows that DMSO as solvent, Et 2-bromoisobutyrate (EBIB) and fluorescein (FL) as catalyst, and [A]0/[EBIB]0/[FL]0 = 200/1/0.1 in the period of 5 h at 47°C are suitable conditions for the reaction. In this way, the yield of the polymer is 24.5%. The glass transition temperature and m.p. of polyacrolein characterized by differential scanning calorimetry are 115.5°C and 165.7°C, resp. At low conversion, the polymerization conforms to be the first-order kinetics reaction. The dependence of polymerization on light source is proved by “on/off” light source experiment In short, this study opens up a new way for the ATRP of acrolein, and the polyacrolein with abundant aldehyde groups can be used in the fields of biomedical labeling, immobilization carrier and adsorption of organic amines.
Quality Control of 5445-17-0, Methyl 2-bromopropionate, also known as Methyl 2-bromopropionate, is a useful research compound. Its molecular formula is C4H7BrO2 and its molecular weight is 167 g/mol. The purity is usually 95%.
Methyl 2-bromopropionate is used in the synthesis of poly(ADP-Ribose)polymerase inhibitors derived from benzoxazin-3-one. Also used in the synthesis of 5-HT2C antagonists affecting serotonin levels.
Methyl 2-bromopropanoate is a chemical compound that can be synthesized in an asymmetric manner. The reaction of methyl 2-bromopropanoate with hydrochloric acid gives the corresponding carboxylic acid, methyl propanoate, and hydrogen bromide in a 1:1 ratio. It has been shown that methyl 2-bromopropanoate is a potential catalyst for the reduction of chloride to chloride ion via the borohydride reduction method. Methyl 2-bromopropanoate has also been used as a model system for studying halides and copper complexes. Magnetic resonance spectroscopy studies have revealed that this chemical compound has a high redox potential and kinetic properties., 5445-17-0.
