Chemical Structure
Description
CATO manufactures Cefoperazone Impurity 61 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.
CATO supplies Cefoperazone Impurity 61 (CAS CATO-C4X-114961), a pharmacopoeial impurity reference standard (molecular formula C50H54N18O16S4, MW 1291.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C50H54N18O16S4, Cefoperazone Impurity 61 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1291.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
