The occurrence of n-(4-Bromophenyl)-3,4-dichlorobenzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, 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.
n-(4-Bromophenyl)-3,4-dichlorobenzenesulfonamide (CAS 1902-15-4) is a high-purity analytical reference standard with the molecular formula C12H8BrCl2NO2S and a molecular weight of 381.07 g/mol.
n-(4-Bromophenyl)-3,4-dichlorobenzenesulfonamide (C12H8BrCl2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
