4-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)-N-pentylbenzenesulfonamide CAS 61633-13-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)-N-pentylbenzenesulfonamide.

4-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)-N-pentylbenzenesulfonamide (CAS 61633-13-4) is a high-purity analytical reference standard with the molecular formula C15H18N2O4S and a molecular weight of 322.38 g/mol.

The molecular framework of 4-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)-N-pentylbenzenesulfonamide (C15H18N2O4S) is characterized by a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
