Cefotaxime Impurity 92 CAS 1201851-24-2

Description

The occurrence of Cefotaxime Impurity 92 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Cefotaxime Impurity 92 (CAS 1201851-24-2), a pharmacopoeial impurity reference standard (molecular formula C6H8N4O2S, MW 200.22 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C6H8N4O2S, Cefotaxime Impurity 92 contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.22 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.
