Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 150.56 g/mol gives Ethyl 3-chloro-2-oxopropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 3-chloro-2-oxopropanoate (CAS 65868-37-3), a certified reference material (molecular formula C5H7ClO3, MW 150.56 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 3-chloro-2-oxopropanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Ethyl 3-chloro-2-oxopropanoate 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.
