| Sources/Uses |
Dimethyl sulfide is a common air pollutant of paper mills, sewage treatment plants, and oil refineries. It is used as a food flavoring agent. [ACGIH] Also used as a chemical intermediate, a sulfiding agent, an anti-coking agent, a gas odorant, and a mineral salt solvent; [CHEMINFO] |

| Comments |
Liquid can cause first degree burns after short contact. [CHRIS] Decomposes on heating to release hydrogen sulfide and sulfur oxides; [ICSC] Low toxicity after skin or inhalation exposure; [HSDB] When applied to the skin, under a patch, for 48 hours, 1% dimethyl sulfide in petroleum jelly does not cause skin irritation. Dimethyl sulfide vapor can reach high concentrations at room temperature and act as a simple asphyxiant. It is a skin and respiratory tract irritant and can cause CNS depression after heavy inhalation exposure. Workers exposed to concentrations below 6% (60,000 ppm) may suffer respiratory collapse and death. [CHEMINFO] |
