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.

Alkyl methyl sulfides have been prepared by disproportionation of symmetrical disulfides with Me2S2 in the presence of NaOH: Chem. Lett., 755 (1999).
