Dimethyl disulfide CAS#624-92-0
Dimethyl disulfide has a diffuse intense onion odor. It is nonlachrymatory. Ironically, although many find its odor objectionable at high concentrations as noted above, when diluted, its aroma has also been described as pleasant. Dimethyl disulfide is often used in combination with other flavor compounds in food products, including baked goods, cheese, frozen dairy products, meat products, soups, savory flavors, fruit flavors, soft candy, gelatin, puddings, and both alcoholic and nonalcoholic beverages.

Product Application of Dimethyl disulfide CAS#624-92-0
Dimethyl disulfide is used as an intermediate as well as a food additive in onion, garlic, cheese, meats, soups, savory flavors and fruit flavors. It is used in oil refineries as a sulfiding agent. It is used to alfa substitute 2-methylfuran-acrolein to produce food stuff. It is involved in the preparation of 4-(methylthio)phenol. Further, it is used to replace methyl mercaptan as a jet fuel additive. It finds application in artificial flavoring agent and a corrosion inhibitor. In addition to this, it serves as an effective soil fumigant in agriculture.
