Description

Methyl sulfide has an unpleasant odor of wild radish that is cabbage- like. It can be tolerated as a green vegetable note only at very low levels (0.1 - 3.0 ppm). It may be produced by reaction of potassium sulfide with methyl chloride in methanol solution; from potassium methyl sulfate and potassium sulfide.
