Ceftizoxime Impurity 41 CAS CATO-C4X-179341

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ceftizoxime Impurity 41.

CATO supplies Ceftizoxime Impurity 41 (CAS CATO-C4X-179341), a pharmacopoeial impurity reference standard (molecular formula C12H15N5O5S2, MW 373.41 g/mol) used for the identification and quantification of trace impurities in APIs.

Ceftizoxime Impurity 41 (C12H15N5O5S2) contains a nitrogen-containing heterocyclic scaffold, 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 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 Ceftizoxime Impurity 41 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.
