Chemical Structure
Description
4-Bromo-N-(4-chloro-3-methylphenyl)benzenesulfonamide (C13H11BrClNO2S) 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).
4-Bromo-N-(4-chloro-3-methylphenyl)benzenesulfonamide (CAS 1266466-05-0) is a high-purity analytical reference standard with the molecular formula C13H11BrClNO2S and a molecular weight of 360.65 g/mol.
