Ceftriaxone EP Impurity C CAS CATO-C4X-116342

Description

Compared with other compounds in its class, the molecular weight of 159.17 g/mol gives Ceftriaxone EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ceftriaxone EP Impurity C (CAS CATO-C4X-116342), a pharmacopoeial impurity reference standard (molecular formula C4H5N3O2S, MW 159.17 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Ceftriaxone EP Impurity C (C4H5N3O2S) is characterized by an amide group, a sulfone group, a carboxylic acid 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 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 Ceftriaxone EP Impurity C 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.
