Dimethyl disulfide (DMDS) is an organic chemical compound with the molecular formula CH3SSCH3 which is the simplest disulfide. It is a flammable liquid with an unpleasant odor.
DMDS can be produced by the reaction of methanethiol with sulfur:
DMDS is used as a food additive in onion, garlic, cheese, meats, soups, savory flavors, and fruit flavors.[2]
Industrially, DMDS is used in oil refineries as a sulfiding agent.[3]
