Ceftizoxime Impurity 92 CAS CATO-C4X-179392

Description

Compared with other compounds in its class, the molecular weight of 416.86 g/mol gives Ceftizoxime Impurity 92 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ceftizoxime Impurity 92 (CAS CATO-C4X-179392) is a certified pharmaceutical impurity reference standard with the molecular formula C14H13ClN4O5S2 and a molecular weight of 416.86 g/mol.

Based on its molecular formula C14H13ClN4O5S2, Ceftizoxime Impurity 92 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 416.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
