| Description | 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. |
| Uses | Industrially, Dimethyl disulfide is also used as a sulfiding agent to catalyze reactions in oil refineries and other industries. It has a low flash point of 16 ℃ (61 °F) that presents fire hazards during refinery usage. Due to its strong odor and low flash point, Dimethyl disulfide typically requires storage under nitrogen pressure in closed containers.
Dimethyl disulfide has a sulfurous odor similar to that of garlic and decaying fish. Because of the distinctive odor of sulfur compounds, similar to DMDS, they are often added to natural gas and propane to warn of leaks and protect people. Therefore, the odor of a DMDS fumigation can be mistaken for a gas leak. DMDS has an odor threshold of approximately 7 ppb, which is about 8 times less than the health‐based level considered by the EPA to be safe (55 ppb). |
| Uses | 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. |
