Overview
Dimethyl sulfide (DMS), also known as methylthiomethane, is an organosulfur compound. It is a methyl sulfide, in which the sulfur atom is substituted by two methyl groups, with the chemical formula of (CH3)2S. It is a highly flammable straw-colored liquid, with a boiling point of 37 degrees Celsius, or 99 degrees Fahrenheit. This is a compound that is easily recognized by its foul odor, that is often described as “cabbage like”. Unlike many other organosulfur compounds, this disagreeable odor is present in even low concentrations of DMS. Dimethyl sulfide is the product of dimethylsulfoniopropionate (DMSP) breakdown, and is also the result of bacterial metabolism of methanethiol.

Applications
DMS is used to create surfactants, fabric softeners, water treatment chemicals, agricultural chemicals, drugs, and dyes. As a methylating agent, DMS can introduce a methyl group to oxygen, nitrogen, carbon, sulfur, phosphorous, and some metals.
While DMS is most often used as a methylating agent, it can sometimes be utilized in other contexts including in sulfonation, as a catalyst, as a solvent, and as a stabilizer.
DMS is also used in a range of organic syntheses, including as a reducing agent in ozonolysis reactions. It also has a use as a food flavoring component.
Characteristics and notes
Features & Benefits :
Dimethyl Sulfide is suitable for furnace operating temperatures and only needs one injection point since DMS disperse well throughout the furnace. At the same time it completely decomposes to H2S at 798°C.
Handling :
Avoid formation of aerosol. Do not breathe vapors/dust. For personal protection see section 8. Smoking, eating and drinking should be prohibited in the application area. Take precautionary measures against static discharges. Provide sufficient air exchange and/or exhaust in work rooms. Open drum carefully as content may be under pressure. Dispose of rinse water in accordance with local and national regulations.
Storage :
No smoking. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Observe label precautions. Electrical installations / working materials must comply with the technological safety standards
Safety and SDS
Read the safety data sheet before handling. Wear suitable gloves and eye protection.
