Cefminox Sodium Impurity 10 CAS CATO-C4X-192610 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.

Cefminox Sodium Impurity 10 (CAS CATO-C4X-192610) is a certified pharmaceutical impurity reference standard with the molecular formula C16H23N7O8S3 and a molecular weight of 537.59 g/mol.

Cefminox Sodium Impurity 10 (C16H23N7O8S3) contains a flavonoid core, an amide group, a sulfone 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).

CATO manufactures Cefminox Sodium Impurity 10 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.
