Vitamin K1 Impurity 62 CAS CATO-C4X-220762 chemical structure

Description

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.

Vitamin K1 Impurity 62 (CAS CATO-C4X-220762) is a certified pharmaceutical impurity reference standard with the molecular formula C16H18O2 and a molecular weight of 242.31 g/mol.

Vitamin K1 Impurity 62 (C16H18O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).

CATO manufactures Vitamin K1 Impurity 62 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.
