Apricoxib CAS 197904-84-0

Description

Compared with other compounds in its class, the molecular weight of 356.44 g/mol gives Apricoxib distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Apricoxib (CAS 197904-84-0), a certified reference material (molecular formula C19H20N2O3S, MW 356.44 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Apricoxib is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
