2-Fluoro-4-(3-methyl-2,5-dioxo-3-phenylpyrrolidin-1-yl)benzenesulfonamide CAS 31150-98-8

Description

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.

2-Fluoro-4-(3-methyl-2,5-dioxo-3-phenylpyrrolidin-1-yl)benzenesulfonamide (CAS 31150-98-8) is a high-purity analytical reference standard with the molecular formula C17H15FN2O4S and a molecular weight of 362.38 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Fluoro-4-(3-methyl-2,5-dioxo-3-phenylpyrrolidin-1-yl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
