Chemical Structure

Topiramate Impurity 10 CAS 66900-93-4 chemical structure

Description

CATO supplies Topiramate Impurity 10 (CAS 66900-93-4), a pharmacopoeial impurity reference standard (molecular formula C9H16O6, MW 220.22 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Topiramate Impurity 10 (C9H16O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 220.22 g/mol, it falls into the medium-molecular-weight range.

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 10 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.
