| | S-Methyl methanethiolsulfonate Usage And Synthesis |
| Chemical Properties | Light Yellow Liquid | | Uses | S-Methyl methanethiosulfonate was used as sulfenylating agent for β-keto sulfoxides, methylene compounds, half-esters of malonic acids and aryl Grignard reagents. It was also used as a reagent to trap the natural thiol-disulfide state of the proteins. | | Uses | S-Methyl methanethiolsulfonate is used for the rapid and selective modification of sulfhydryl groups of enzymes and it is also useful for mapping the pore-lining regions of the ryanodine receptor. | | Uses | carbonyl reactive homobifunctional cross-linking reagent cleavable with periodate | | Definition | ChEBI: A sulfonic acid derivative obtained by condensaton of methanesulfonic acid with methanethiol. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 49, p. 2281, 1984 DOI: 10.1021/jo00186a039
