Description and Uses

Benzene sulfonic acid is an organo sulfur compound with the formula C6H5SO3H. It is the simplest aromatic sulfonic acid. It forms colorless deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in carbon disulfide and diethyl ether. It is often stored in the form of alkali metal salts. Its aqueous solution is strongly acidic.

Benzenesulfonic acid is an aryl sulfonic acid that can be used to form an organic salt with 5,7-dimethyl-1,8-naphthyridine-2-amine, that can be a synthon for developing supramolecular structures. It can also act as a dopant for the polymerization of pyrrole to form poly(pyrrole), a conducting polymer useful in the development of flexible capacitors.
