Benzenesulfonic Acid (conjugate to base and benzenesulfonate) is an organic sulfur compound that has a formula that is C6H6O3S. It is the most basic aromatic sulfuric acid. It forms white deliquescent crystals or a white, waxy solid that dissolves in ethanol and water. It is little soluble in benzene but not soluble in solvents that are nonpolar, such as diethyl ether. It is usually stored in the alkali metal salts. Its solution in aqueous form is extremely acidic.
4-[(2,4-Dihydroxyphenyl)azo]benzenesulfonic acid belongs to the class of organic compounds known as azobenzenes. These are aromatic compounds made of organonitrogen with the azo group as its central component that is composed of nitrogen atoms, and each is bonded to the benzene rings. Based on a literature review very few articles have been published on 4-[(2,4-Dihydroxyphenyl)azo]benzenesulfonic acid.
