The occurrence of Topiramate Impurity 20 is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Topiramate Impurity 20 (CAS 38029-84-4), a pharmacopoeial impurity reference standard (molecular formula C6H12O6, MW 180.16 g/mol) used for the identification and quantification of trace impurities in APIs.
Topiramate Impurity 20 (C6H12O6) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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 20 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.
