Vinyl bromides undergo the Heck reaction, which involves C-C coupling with alkene to give substituted alkenes. 4897-84-1, formula is C5H9BrO2, Name is Methyl 4-bromobutanoate. Methyl bromide is a precursor in the manufacture of several chemicals and is employed as a soil sterilant, mainly for seed production. COA of Formula: C5H9BrO2.
Tomer, Sanjiv O.;Soni, Hemant P. research published 《 Cinchona alkaloid derivative modified Fe3O4 nanoparticles for enantioselective ring opening of meso-cyclic anhydrides》, the research content is summarized as follows. In the present work, the mol. framework of quinidine was modified at the methoxy functional group of the C6′ carbon of the quinoline moiety with a long-chain carboxylic acid group (-COOH) and it was used as a capping agent during the synthesis of Fe3O4 NPs. The resulting modified quinidine capped Fe3O4 (Fe3O4@mQD) NPs were characterized by different techniques and used for enantioselective ring opening (ERO) by methanolysis in a heterogeneous mode of catalysis. The interactions of mQD with the Fe3O4 surface, as well as its % loading, were studied using FTIR spectroscopy and thermal anal. techniques. Reaction parameters like the solvent system, temperature, and substrate were optimized. ERO of succinic and glutaric anhydrides by methanolysis was carried out in the presence of Fe3O4@mQD NPs. The optimized protocol can produce a chiral hemiester with high enantioselectivity (up to 98% ee) and excellent % yield (more than 90% in most of the cases).
4897-84-1, Methyl 4-bromobutyrate,also as known as 4-Bromobutyric acid methyl ester, is a useful research compound. Its molecular formula is C5H9BrO2 and its molecular weight is 181.03 g/mol. The purity is usually 95%.
4-Bromobutyric acid methyl ester is a synthetic compound that can be used to inhibit the activity of the G1 phase cyclin-dependent kinases. It has been shown to inhibit protein synthesis by alkylating the amino groups of proteins and fatty acids. 4-Bromobutyric acid methyl ester also inhibits the growth of cancer cell lines, such as renal carcinoma cells. The mechanism of action for this drug is not well understood, but it may be due to its ability to bind with monoclonal antibodies and enter kidney cells by passive diffusion., COA of Formula: C5H9BrO2
