Vinyl bromides undergo the Heck reaction, which involves C-C coupling with alkene to give substituted alkenes. 70-23-5, formula is C5H7BrO3, Name is Ethyl 3-bromo-2-oxopropanoate. Methyl bromide is a precursor in the manufacture of several chemicals and is employed as a soil sterilant, mainly for seed production. Quality Control of 70-23-5.
Savari, Mehdi;Varasteh-Moradi, Ali;Sayyed-Alangi, S. Zahra;Hossaini, Zinatossadat;Zafarmehrabian, Ramin research published 《 Ag/Fe3O4/TiO2@MWCNTs as a reusable organometallic nanocatalyst promoted green synthesis of new pyridobenzoazepines: Study of biological activity and reduction of organic pollutants》, the research content is summarized as follows. In this research, Ag/Fe3O4/TiO2@MWCNTs magnetic nanocomposites synthesized using water extract of Spinacia oleracea leaves, and the high performance of synthesized catalyst was confirmed by employing it in the multicomponent reaction of isatoic anhydride, N-methylimidazole, α-haloketones, electron-deficient acetylenic compounds, ammonium acetate, and Me epoxide in water at ambient temperature for the preparation of new pyridobenzoazepine derivatives such as I [X = H, Me, NO2, etc.; R1 = Me, Et; R2 = CO2Et, 4-MeC6H4, 4-MeOC6H4, etc.] in high yields. Also, the catalytic activity of the green synthesized Ag/Fe3O4/TiO2@MWCNTs was evaluated in the reduction of organic pollutants such as 4-nitrophenol in water at mild conditions. The results indicated that the biosynthesized magnetic nanocomposites (MNCs) have very high and effective catalytic activity for organic pollutants within few seconds. The synthesized compounds have OH group in their structure and for this reason might be showed good antioxidant activity. Also, employing Gram-pos. and Gram-neg. bacteria in the disk diffusion procedure confirmed antimicrobial effect of the some pyridobenzoazepine derivatives The results showed that synthesized compounds prevented the bacterial growth. This used procedure for preparation of pyridobenzoazepine derivatives have some advantages such as low reaction time, product with high yields, and simple separation of catalyst and products.
Quality Control of 70-23-5, Ethyl bromopyruvate molecular formula is C5H7BrO3 and its molecular weight is 195.01 g/mol. The purity is usually 95%.
Ethyl bromopyruvate is used in a synthesis of thioxothiazolidines from carbon disulfide and primary amines.
Ethyl bromopyruvate is a chemical inhibitor that inhibits the enzyme pyruvate dehydrogenase, which is responsible for the conversion of pyruvic acid to acetyl-CoA. This inhibition leads to a decrease in ATP levels and can cause metabolic disorders. Ethyl bromopyruvate is used as an anthelmintic drug and in asymmetric synthesis. It is also used in the synthesis of thiostrepton, an antibiotic that has been shown to have antimicrobial activity against Gram-positive bacteria, including Staphylococcus aureus and Streptococcus pneumoniae., 70-23-5.
