Product Application
Dimethyl disulfide serves as a chemical intermediate and food additive for onion, garlic, cheese, meats, soups, savory flavors and fruit flavors. It functions as a sulfiding agent in oil refineries. It is used to react 2-methylfuran-acrolein to produce food ingredients. It participates in the synthesis of 4-(methylthio)phenol. It replaces methyl mercaptan as a jet fuel additive. It is used as artificial flavoring agent and corrosion inhibitor. In agriculture, it acts as an effective soil fumigant.
