Chemical Structure

4-(2-Formylphenoxy)benzenesulfonamide CAS 902837-00-7 chemical structure

Description

4-(2-Formylphenoxy)benzenesulfonamide (C13H11NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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-(2-Formylphenoxy)benzenesulfonamide (CAS 902837-00-7), molecular formula C13H11NO4S and molecular weight 277.30 g/mol, is a CATO reference standard with documented purity and traceability.
