Chemical Structure
Description
As a process- or degradation-related impurity, Cefathiamidine Impurity 3 (CAS 1417570-09-2, C17H26N4O4S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Cefathiamidine Impurity 3 (C17H26N4O4S2) 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.
As a certified reference material (CRM), Cefathiamidine Impurity 3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
