Chemical Structure

N-(Benzenesulfonyl)-N-(1-benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)benzenesulfonamide CAS 478033-05-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 505.61 g/mol gives N-(Benzenesulfonyl)-N-(1-benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N-(Benzenesulfonyl)-N-(1-benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)benzenesulfonamide (CAS 478033-05-5), a certified reference material (molecular formula C26H23N3O4S2, MW 505.61 g/mol) for analytical method development and quality control.

The molecular framework of N-(Benzenesulfonyl)-N-(1-benzyl-3-cyano-4,5-dimethyl-1H-pyrrol-2-yl)benzenesulfonamide (C26H23N3O4S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
