Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 541.60 g/mol gives Cefetamet Impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Cefetamet Impurity 7 (CAS 1705612-80-1, C21H27N5O8S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Cefetamet Impurity 7 (C21H27N5O8S2) 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 Cefetamet Impurity 7 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.
