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.
