methanesulfonates การใช้

• Methanesulfonates are occasionally used as a protecting group for alcohols.
• The simplest organic sulfonyl chloride, it is used to make methanesulfonates and to generate the elusive molecule sulfene.
• Salts and esters of methanesulfonic acid are known as mesylates ( or methanesulfonates, as in ethyl methanesulfonate ).
• The anhydrous salt is formed by water loss at 120 癈 . Similar methanesulfonates can be prepared with other lanthanides.
• Due to the high standard electrode potentials of both zinc and cerium redox reactions in aqueous media, the open-circuit cell voltage is as high as 2.43 V . Methanesulfonic acid is used as supporting electrolyte, as it allows high concentrations of both zinc and cerium; the solubility of the corresponding methanesulfonates is 2.1 M for Zn, 2.4 M for Ce ( III ) and up to 1.0 M for Ce ( IV ).
