Cefotaxime Impurity 50 CAS CATO-C4X-120150

Description

Compared with other compounds in its class, the molecular weight of 412.44 g/mol gives Cefotaxime Impurity 50 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Cefotaxime Impurity 50 (CAS CATO-C4X-120150), a pharmacopoeial impurity reference standard (molecular formula C15H16N4O6S2, MW 412.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C15H16N4O6S2, Cefotaxime Impurity 50 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 412.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
