German chemist Hermann Kolbe discovered MSA between 1842 and 1845 and originally termed it methyl hyposulphuric acid. [4] [5] [6]The discovery stemmed from earlier work by Berzelius and Marcet in 1813, who treated carbon disulfide with moist chlorine and produced a compound they named "sulphite of chloride of carbon".
The sulfonate ion. In organosulfur chemistry, a sulfonate is a salt, anion or ester of a sulfonic acid. Its formula is R−S(=O) 2 −O −, containing the functional group −S(=O) 2 −O −, where R is typically an organyl group, amino group or a halogen atom. Sulfonates are the conjugate bases of sulfonic acids.
It was also used in Takahashi Taxol total synthesis and in chemical glycosylation reactions. [5]Trimethylsilyl trifluoromethanesulfonate has a variety of other specialized uses.
Many method have been developed for introducing sulfonate groups aside from direction sulfonation. A classic named reaction is the Piria reaction (Raffaele Piria, 1851) in which nitrobenzene is treated with a metal bisulfite forming an aminosulfonic acid as a result of combined nitro group reduction and sulfonation.

General structure of a sulfonic acid with the functional group indicated in blue. In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide.
