Description
CATO supplies Cefpodoxime impurity 68 (CAS CATO-C4X-157968), a pharmacopoeial impurity reference standard (molecular formula C35H40N10O14S4, MW 953.01 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Cefpodoxime impurity 68 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 953.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Cefpodoxime impurity 68 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.
