Description
CATO supplies Cefdinir Impurity 40 (CAS 1330164-22-1), a pharmacopoeial impurity reference standard (molecular formula C13H11N3O6S, MW 337.31 g/mol) used for the identification and quantification of trace impurities in APIs.
Cefdinir Impurity 40 (C13H11N3O6S) contains a nitrogen-containing heterocyclic scaffold, 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 Cefdinir Impurity 40 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.
