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.
CATO supplies Cefoperazone Impurity N6 (CAS 82778-05-0), a pharmacopoeial impurity reference standard (molecular formula C15H16N3O6Na, MW 357.30 g/mol) used for the identification and quantification of trace impurities in APIs.
Cefoperazone Impurity N6 (C15H16N3O6Na) contains a flavonoid core, an amide 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).
As a certified reference material (CRM), Cefoperazone Impurity N6 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.
