Chemical Structure
Description
The occurrence of 1-(4-Bromobenzenesulfonyl)-N-(4-chlorophenyl)pyrrolidine-2-carboxamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-Bromobenzenesulfonyl)-N-(4-chlorophenyl)pyrrolidine-2-carboxamide (CAS 317377-68-7), molecular formula C17H16BrClN2O3S and molecular weight 443.74 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Bromobenzenesulfonyl)-N-(4-chlorophenyl)pyrrolidine-2-carboxamide (C17H16BrClN2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
