Cefditoren Impurity 59 CAS CATO-C4X-135859 chemical structure

Description

Cefditoren Impurity 59 (CAS CATO-C4X-135859) is a certified pharmaceutical impurity reference standard with the molecular formula C25H23N9O7S4 and a molecular weight of 689.77 g/mol.

Cefditoren Impurity 59 (C25H23N9O7S4) 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).

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 Cefditoren Impurity 59 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.
