Application: Benzenesulfonic acid is an aryl sulfonic acid that can be used:• As an oxidizing agent in the synthesis of Fe(III) benzenesulfonate.
• As a catalyst during the vapor-phase nitration of benzene.
• As a reagent in the synthesis of organic salts.
• To form an organic salt with 5,7-dimethyl-1,8-naphthyridine-2-amine, that can be a synthon for developing supramolecular structures.
• As a dopant for the polymerization of pyrrole to form poly(pyrrole), a conducting polymer useful in the development of flexible capacitors.
General description: Benzenesulfonic acid (BSA), also known as phenylsulfonic acid, is the simplest aromatic sulfonic acid. It is also used as a catalyst for Michael′s reactions and in the oxidative alkenylation process.
