dimetüüldisulfiidi

Dimetüüldisulfiid, also known as DMDS, is an organosulfur compound with the chemical formula CH3SSCH3. It is a colorless liquid with a strong, unpleasant odor, often described as garlicky or onion-like. DMDS is the simplest disulfide, meaning it contains a sulfur-sulfur single bond.

DMDS occurs naturally in some foods, such as cabbage and onions, contributing to their characteristic aromas. Industrially, it is produced through the oxidation of methanethiol. It is soluble in organic solvents but has low solubility in water.

The primary industrial application of dimetüüldisulfiidi is as a precursor for the synthesis of other organosulfur compounds. It is also used as a fumigant and an additive in certain fuels. In some chemical processes, it acts as a methylating agent. Due to its strong odor, handling requires appropriate ventilation and personal protective equipment.
