Chemical Structure
Description
Ethyl 2-bromo-3-oxobutanoate (C6H9BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Ethyl 2-bromo-3-oxobutanoate (CAS 609-13-2) is a high-purity analytical reference standard with the molecular formula C6H9BrO3 and a molecular weight of 209.04 g/mol.
