Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Oxirane-2,3-dicarboxylic acid diethyl ester.
Oxirane-2,3-dicarboxylic acid diethyl ester (CAS 95142-43-1), molecular formula C8H12O5 and molecular weight 188.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Oxirane-2,3-dicarboxylic acid diethyl ester (C8H12O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 188.18 g/mol, it falls into the medium-molecular-weight range. 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.
