One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine. 70-23-5, formula is C5H7BrO3, Name is Ethyl 3-bromo-2-oxopropanoate, HPLC of Formula: 70-23-5
Rostamian, Rezvaneh;Khalilzadeh, Mohammad A.;Zareyee, Daryoush research published 《 Wood ash biocatalyst as a novel green catalyst and its application for the synthesis of benzochromene derivatives》, the research content is summarized as follows. This study investigates the catalytic activity of wood ash as a heterogeneous catalyst for the synthesis of benzochromene derivatives I (R = Me, 4-methoxyphenyl, Ph, Et, 4-methylphenyl; R1 = 4-methoxyphenyl, C(O)OC2H5, 4-methylphenyl). Several wood ash catalysts, comprising calcium- and potassium-rich carbonates, were prepared from different natural resources under various combustion temperatures The prepared catalysts were characterized by Fourier transform IR, SEM, energy dispersive X-ray anal., transmission electron microscopy, and X-ray diffraction techniques. Catalytic efficiency of the resultant catalysts was tested in the synthesis of benzochromene derivatives I. The exptl. studies clarified that the catalyst prepared at 850°C could efficiently expedite the formation of three-component synthesis of benzochromene derivatives I in water at 80°C with high yields. Indeed, alkali, alk. metal, and metal oxides such as Al2O3, SiO2, MgO, CaO, and Fe2O3, are widely utilized as both catalyst and catalyst support in the heterogeneous catalytic processes. The prepared wood ash catalysts (possessing metal oxides, e.g., CuO, Al2O3, SiO2, and CaO) could effectively prompt the electrophilic activity of the carbonyl groups during the nucleophilic attack intermediate, enhancing the efficiency of the reactions.
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., HPLC of Formula: 70-23-5
