Chemical Structure
Description
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO supplies Cefepime Impurity 30 (CAS CATO-C4X-119330), a pharmacopoeial impurity reference standard (molecular formula C25H30N9O7S3, MW 664.76 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Cefepime Impurity 30 (C25H30N9O7S3) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 664.76 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 30 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.
