Benzo[d]thiazole-4-sulfonyl chloride (CAS 149575-65-5) is a high-purity analytical reference standard with the molecular formula C7H4ClNO2S2 and a molecular weight of 233.70 g/mol.
Benzo[d]thiazole-4-sulfonyl chloride (C7H4ClNO2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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).
