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 Cefepime Impurity 41 (CAS CATO-C4X-119341), a pharmacopoeial impurity reference standard (molecular formula C27H31N8O7S3, MW 675.78 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Cefepime Impurity 41 (C27H31N8O7S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.5, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 675.78 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Cefepime Impurity 41 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.
