Azelnidipine Impurity 6 CAS 50626-68-1 chemical structure

Description

CATO manufactures Azelnidipine Impurity 6 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.

Azelnidipine Impurity 6 (CAS 50626-68-1) is a certified pharmaceutical impurity reference standard with the molecular formula C20H25N3O6 and a molecular weight of 403.43 g/mol.

Azelnidipine Impurity 6 (C20H25N3O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
