Chemical Structure

Topiroxostat impurity 76 CAS CATO-C4X-105576 chemical structure

Description

As a process- or degradation-related impurity, Topiroxostat impurity 76 (CAS CATO-C4X-105576, C12H9N5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Topiroxostat impurity 76 (C12H9N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Topiroxostat impurity 76 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.
