The occurrence of 2-Bromo-4,6-dichlorobenzenesulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-4,6-dichlorobenzenesulfonyl chloride (CAS 351003-53-7) is a high-purity analytical reference standard with the molecular formula C6H2BrCl3O2S and a molecular weight of 324.41 g/mol.
2-Bromo-4,6-dichlorobenzenesulfonyl chloride (C6H2BrCl3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
