Description

General description

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.
