Chemical Structure

Cefoperazone Impurity 51 CAS 73240-07-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cefoperazone Impurity 51.

CATO supplies Cefoperazone Impurity 51 (CAS 73240-07-0), a pharmacopoeial impurity reference standard (molecular formula C25H29N9O9S2, MW 663.68 g/mol) used for the identification and quantification of trace impurities in APIs.

Cefoperazone Impurity 51 (C25H29N9O9S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Cefoperazone Impurity 51 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.
