Dimethyl disulfide features a strong, diffusive onion‑like scent and does not cause tearing. While many people find its concentrated odor unpleasant, when properly diluted, it can emit a pleasant fragrance. This substance is frequently blended with other flavoring ingredients for foods such as baked goods, cheese, frozen dairy items, meat products, soups, savory seasonings, fruit flavors, soft candies, gelatin, puddings, and both alcoholic and non‑alcoholic drinks.

Product Application of Dimethyl disulfide CAS#624-92-0
Dimethyl disulfide acts as a chemical intermediate and food flavor additive in onion, garlic, cheese, meat, soups, savory flavors, and fruit flavorings. It serves as a sulfiding agent in petroleum refineries. It participates in the synthesis of food ingredients via alpha substitution reactions of 2-methylfuran-acrolein. It is used in manufacturing 4-(methylthio)phenol and can replace methyl mercaptan as a jet fuel additive. It functions as an artificial flavoring agent and corrosion inhibitor. Additionally, it is widely used as an efficient soil fumigant in agricultural applications.
