General description
Dimethyl disulfide (DMDS) is an organic dialkyl disulfide. It is one of the odorous compounds found on the working face of typical municipal solid waste landfill in China. DMDS forms adducts with mono-unsaturated acetates by addition across carbon-carbon double bonds. These adducts are useful to locate the of double bonds in long-chain mono-unsaturated acetates. Adsorption of DMDS on Au(111) surface has been investigated by the density functional theory (DFT) within a generalized gradient approximation and experimental high-resolution electron energy loss spectroscopy (HREELS) techniques.
Application
Dimethyl disulfide (DMDS) may be used to derivatize alkenes for the determination of position of double bond by MS. It may also be used to determine the location of the double-bond position of monounsaturated fatty acids in Campylobacter cryaerophila by combined GC-MS analysis.
