Dimethyl Sulfide CAS 75-18-3

Dimethyl sulfide, also known as thiodimethane, is generally a colorless, transparent liquid with an unpleasant odor, which is flammable and volatile. Insoluble in water, soluble in ethanol and ether. Its vapor and air can form an explosive mixture with an explosion limit of 2.2% to 19.7% (volume fraction).

Natural products of Dimethyl sulfide are found in American peppermint, Algerian geranium oil and cream. Easily oxidized to generate sulfoxide or sulfone. It reacts with haloalkane to generate sulfonium salt, which reacts with wet silver hydroxide to generate strong basic compound sulfonium base.

As a reducing agent, borane dimethyl sulfide complex is a convenient and stable source of borane for hydroboration, selective reduction of α-hydroxy esters, etc.

The presence of dimethyl sulfide (DMS) in the atmosphere has long been recognized as an important chemical component in determining the global climate. However, while it may have a slight effect on the early stages of formation, its impact is much more pronounced during the latter stages of carbon dioxide’s rise in concentration.
