BENZENE SULPHONIC ACID, EXTRA PURE

Benzenesulfonic acid, an aromatic sulfonic acid with the chemical formula C₆H₆O₃S, possesses benzenesulfonate as its conjugate base. Representing the simplest aromatic sulfonic acid, it finds diverse applications in various industrial sectors. Notably, benzenesulfonic acid serves as a precursor for phenol production. This conversion can be achieved through two primary methods: fusion with sodium hydroxide or hydrolysis of its salts, typically sodium salts. Furthermore, benzenesulfonic acid plays a crucial role in the synthesis of surfactants, which are often derived from its metal or amine salts. Additionally, benzenesulfonate ions can function as counterions for specific cationic pharmaceuticals.
