Amfani
Methanesulfonic acid shine mafi sauƙin sinadarin alkyl sulfonic acid. Ruwa mara launi. Mai sauƙin narkewa a cikin ruwa, yana narkewa kaɗan a cikin sinadarai masu narkewa na halitta. Ƙarfin acid mai ƙarfi tare da pKa na -0.6. Ba a haɗa shi da ruwa a cikin ruwan zafi ko maganin alkaline mai zafi ba. Ana iya samar da Methanesulfonic acid ta hanyar oxidation na methyl mercaptan ko dimethyl disulfide tare da oxygen ko nitric acid. Hakanan ana iya shirya shi ta hanyar maganin sodium sulfite da dimethyl sulfate a cikin ruwa a zafin 100 ° C.
