Chemical Structure

Topiramate Impurity 31 CAS CATO-C4X-176831 chemical structure

Description

CATO supplies Topiramate Impurity 31 (CAS CATO-C4X-176831), a pharmacopoeial impurity reference standard (molecular formula C15H26O9S, MW 382.43 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Topiramate Impurity 31 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 382.43 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).

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.

CATO manufactures Topiramate Impurity 31 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.
