Epalrestat Impurity 25 CAS 15174-47-7 chemical structure

Description

CATO manufactures Epalrestat Impurity 25 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Epalrestat Impurity 25 (CAS 15174-47-7), a pharmacopoeial impurity reference standard (molecular formula C10H10O, MW 146.19 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Epalrestat Impurity 25 (C10H10O) contains 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 146.19 g/mol, it falls into the low-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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
