Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 164.59 g/mol gives 2-Chloroethyl 3-oxobutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Chloroethyl 3-oxobutanoate (CAS 54527-68-3), a certified reference material (molecular formula C6H9ClO3, MW 164.59 g/mol) for analytical method development and quality control.
2-Chloroethyl 3-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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Chloroethyl 3-oxobutanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
