Chemical Structure

N-Benzyl-4-(4-cyano-5-(dimethylamino)oxazol-2-yl)-N-methylbenzenesulfonamide CAS 941240-71-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Benzyl-4-(4-cyano-5-(dimethylamino)oxazol-2-yl)-N-methylbenzenesulfonamide.

N-Benzyl-4-(4-cyano-5-(dimethylamino)oxazol-2-yl)-N-methylbenzenesulfonamide (CAS 941240-71-7), molecular formula C20H20N4O3S and molecular weight 396.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-Benzyl-4-(4-cyano-5-(dimethylamino)oxazol-2-yl)-N-methylbenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
