Benzenesulfonic acid is an aryl sulfonic acid that can be used:
- As an oxidizing agent in the synthesis of Fe(III) benzenesulfonate. [2]
- As a catalyst during the vapor-phase nitration of benzene. [3]
- As a reagent in the synthesis of organic salts. [4]
- To form an organic salt with 5,7-dimethyl-1,8-naphthyridine-2-amine, that can be a synthon for developing supramolecular structures.[4]
- As a dopant for the polymerization of pyrrole to form poly(pyrrole), a conducting polymer useful in the development of flexible capacitors.[5]
