Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-2-thioxooxazolidin-4-one.
3-Ethyl-2-thioxooxazolidin-4-one (CAS 10574-66-0) is a high-purity analytical reference standard with the molecular formula C5H7NO2S and a molecular weight of 145.18 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Ethyl-2-thioxooxazolidin-4-one is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 3-Ethyl-2-thioxooxazolidin-4-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.
