Chemical Structure
Description
The occurrence of 4-(3-(2-Chlorophenyl)-3-methyl-2,5-dioxopyrrolidin-1-yl)benzenesulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(3-(2-Chlorophenyl)-3-methyl-2,5-dioxopyrrolidin-1-yl)benzenesulfonamide (CAS 65116-66-7), a certified reference material (molecular formula C17H15ClN2O4S, MW 378.83 g/mol) for analytical method development and quality control.
The molecular framework of 4-(3-(2-Chlorophenyl)-3-methyl-2,5-dioxopyrrolidin-1-yl)benzenesulfonamide (C17H15ClN2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
