Chemical Structure
Description
As a certified reference material (CRM), (S)-4-(2-chloroacetyl)oxazolidin-2-one 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.
(S)-4-(2-chloroacetyl)oxazolidin-2-one (CAS 244793-72-4) is a high-purity analytical reference standard with the molecular formula C5H6ClNO3 and a molecular weight of 163.56 g/mol.
(S)-4-(2-chloroacetyl)oxazolidin-2-one (C5H6ClNO3) contains an amide group, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
