Compared with other compounds in its class, the molecular weight of 150.56 g/mol gives Ethyl 2-Chloro-3-oxopropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 2-Chloro-3-oxopropanoate (CAS 33142-21-1), a certified reference material (molecular formula C5H7ClO3, MW 150.56 g/mol) for analytical method development and quality control.
Ethyl 2-Chloro-3-oxopropanoate (C5H7ClO3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl 2-Chloro-3-oxopropanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
