N-(4,5-Dimethoxy-2-(5-methylfuran-2-carbonyl)phenyl)-4-methylbenzenesulfonamide CAS 886493-76-1

Description

N-(4,5-Dimethoxy-2-(5-methylfuran-2-carbonyl)phenyl)-4-methylbenzenesulfonamide (CAS 886493-76-1), molecular formula C21H21NO6S and molecular weight 415.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-(4,5-Dimethoxy-2-(5-methylfuran-2-carbonyl)phenyl)-4-methylbenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 415.46 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.
