Dimethyl Sulfide (DMS) is a low molecular weight sulfur compound with a distinctive garlic-like odor. It possess a low level of toxicity, and is used as a flavor component in the US and other parts of the world.
Exact-S® Dimethyl Sulfide has applications in the hydrocarbon industry, including the production of ethylene. Dimethyl Sulfide is also used in certain chemical reactions of importance to the pharmaceutical Industry.
Key Applications for Dimethyl Sulfide
Exact-S® Dimethyl Sulfide has been the gold standard in presulfiding and ethylene applications for over twenty years. It offers an economical combination of low toxicity and high sulfur content for use in the petrochemical industry.
Exact-S is the most widely used agent for presulfiding of hydrodenitrification (HDN), Hydrodesulfurization (HDS) and cracking catalysts.
Key Applications for Exact-S® DMS
Dimethyl Sulfide (DMS) has several applications as both a solvent (organometallic reactions) and a reagent (BH3-DMS adduct, trimethylsulfonium halide salts).
The dramatic effect of DMS in certain conjugate addition reactions was recently described by Jess Dambacher and Mikael Bergdahl of San Diego University (J.Org Chem. 70 (2), 580-589 (2005). They demonstrated that Gilman-type silylcuprates add in high yield to α,ß-unsaturated carbonyl compounds in high chemical yield and diastereomeric ratio of the products:
