Ethyl (2s)-2-chloropropanoate CAS 74497-15-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Ethyl (2s)-2-chloropropanoate (CAS 74497-15-7) is a high-purity analytical reference standard with the molecular formula C5H9ClO2 and a molecular weight of 136.58 g/mol.

Ethyl (2s)-2-chloropropanoate (C5H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

As a certified reference material (CRM), Ethyl (2s)-2-chloropropanoate 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.
