Celecoxib Impurity 12 CAS 1061214-09-2

Description

Compared with other compounds in its class, the molecular weight of 384.37 g/mol gives Celecoxib Impurity 12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Celecoxib Impurity 12 (CAS 1061214-09-2), a pharmacopoeial impurity reference standard (molecular formula C17H15F3N2O3S, MW 384.37 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C17H15F3N2O3S, Celecoxib Impurity 12 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 384.37 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).

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.
