Ceftizoxime Impurity 74(isomers mixture) CAS 94088-75-2

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 74(isomers mixture).

Ceftizoxime Impurity 74(isomers mixture) (CAS 94088-75-2) is a certified pharmaceutical impurity reference standard with the molecular formula C13H10N4O2S3 and a molecular weight of 350.44 g/mol.

The molecular framework of Ceftizoxime Impurity 74(isomers mixture) (C13H10N4O2S3) 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 Ceftizoxime Impurity 74(isomers mixture) 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.
