General description
S-Methyl methanethiosulfonate is a reagent used to synthesize thiols and thioesters. Used as cross-linking agent to prepare polymer networks. Interaction of S-methyl methanethiosulfonate (MMTS) with dipalmitoylphosphatidylcholine (DPPC) bilayers has been investigated by FTIR and surface-enhanced Raman spectroscopy.
Application
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.
