Ball-and-stick model of methanesulfonic acid.. Aryl sulfonic acids are produced by the process of sulfonation.Usually the sulfonating agent is sulfur trioxide.A large scale application of this method is the production of alkylbenzenesulfonic acids:

Methanesulfonic acid (MsOH, MSA) or methanesulphonic acid (in British English) is an organosulfuric, colorless liquid with the molecular formula CH 3 SO 3 H and structure H 3 C−S(=O) 2 −OH. It is the simplest of the alkylsulfonic acids ( R−S(=O) 2 −OH ).
Sulfonation gives the "alpha" product naphthalene-1-sulfonic acid as the kinetic product but naphthalene-2-sulfonic acid as the thermodynamic product. The 1-isomer forms predominantly at 25 °C, and the 2-isomer at 160 °C. Sulfonation to give the 1- and 2-sulfonic acid occurs readily: H 2 SO 4 + C 10 H 8 → C 10 H 7 SO 3 H + H 2 O
Ethanedisulfonic acid is a diprotic sulfonic acid, with pKa values of -1.46 and -2.06, making it a very strong acid. When used in pharmaceutical formulations , the salts with the active ingredient are known as edisylates .
Perfluorobutanesulfonic acid (PFBS) is a PFAS chemical compound having a four-carbon fluorocarbon chain and a sulfonic acid functional group. It is stable and unreactive because of the strength of carbon–fluorine bonds. It can occur in the form of a colorless liquid or a corrosive solid. [1]
2,3-Dimercapto-1-propanesulfonic acid (abbreviated DMPS) and its sodium salt (known as Unithiol) are chelating agents that form complexes with various heavy metals. They are related to dimercaprol , which is another chelating agent.
Cysteic acid also known as 3-sulfo-l-alanine is the organic compound with the formula HO 3 SCH 2 CH(NH 2)CO 2 H. It is often referred to as cysteate, which near neutral pH takes the form − O 3 SCH 2 CH(NH 3 +)CO 2 −. It is an amino acid generated by oxidation of cysteine, whereby a thiol group is fully oxidized to a sulfonic acid/sulfonate ...
