2H-1-Benzopyran-2-one-2,4-13C2, 7-hydroxy-4-methyl- CAS 438187-75-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2H-1-Benzopyran-2-one-2,4-13C2, 7-hydroxy-4-methyl-.

2H-1-Benzopyran-2-one-2,4-13C2, 7-hydroxy-4-methyl- (CAS 438187-75-8) is a high-purity analytical reference standard with the molecular formula C8[13C]2H8O3 and a molecular weight of 178.15 g/mol.

Structurally, 2H-1-Benzopyran-2-one-2,4-13C2, 7-hydroxy-4-methyl- (C8[13C]2H8O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 178.15 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.

As a certified reference material (CRM), 2H-1-Benzopyran-2-one-2,4-13C2, 7-hydroxy-4-methyl- 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.
