Chemical Structure
Description
Ethyl 3-chloro-4-oxobutanoate (C6H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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 3-chloro-4-oxobutanoate (CAS 1290138-70-3), molecular formula C6H9ClO3 and molecular weight 164.59 g/mol, is a CATO reference standard with documented purity and traceability.
