Chlorpromazine Impurity 8 CAS 58-40-2 chemical structure

Description

Chlorpromazine Impurity 8 (CAS 58-40-2) is a certified pharmaceutical impurity reference standard with the molecular formula C17H20N2S and a molecular weight of 284.42 g/mol.

Chlorpromazine Impurity 8 (C17H20N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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 Chlorpromazine Impurity 8 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.
