4-(3-(2,5-Difluorophenyl)-5,5-dimethyl-4-oxo-4,5-dihydrofuran-2-yl)benzenesulfonamide CAS 301693-32-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 379.38 g/mol gives 4-(3-(2,5-Difluorophenyl)-5,5-dimethyl-4-oxo-4,5-dihydrofuran-2-yl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(3-(2,5-Difluorophenyl)-5,5-dimethyl-4-oxo-4,5-dihydrofuran-2-yl)benzenesulfonamide (CAS 301693-32-3) is a high-purity analytical reference standard with the molecular formula C18H15F2NO4S and a molecular weight of 379.38 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 4-(3-(2,5-Difluorophenyl)-5,5-dimethyl-4-oxo-4,5-dihydrofuran-2-yl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.38 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
