Cefoperazone Impurity 40 CAS CATO-C4X-114948

Description

Compared with other compounds in its class, the molecular weight of 1207.23 g/mol gives Cefoperazone Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cefoperazone Impurity 40 (CAS CATO-C4X-114948) is a certified pharmaceutical impurity reference standard with the molecular formula C49H54N14O17S3 and a molecular weight of 1207.23 g/mol.

The molecular framework of Cefoperazone Impurity 40 (C49H54N14O17S3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Cefoperazone 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.
