Products Description of Dimethyl Disulfide CAS#624-92-0
Dimethyl disulfide (DMDS) is an industrial-grade chemical with a purity of ≥99%. It is a flammable yellow liquid with a characteristic sulfur odor.
Key physical properties include a melting point of -84.7°C, a boiling point of 109.6°C, vapor pressure of 3.0×10⁶ mPa at 20°C, relative density of 1.062 at 20°C, and a freezing point of 16°C. It has a low water solubility (2.7 g/L at 20°C) but is miscible with most organic solvents at 15–25°C.
Dimethyl disulfide is thermally stable up to 300°C, though it becomes unstable in the presence of oxidizing agents, making it suitable for various industrial applications.

Product Applications of Dimethyl Disulfide CAS#624-92-0
Dimethyl disulfide (DMDS) is widely used as a chemical intermediate and as a food additive in products such as onion, garlic, cheese, meats, soups, savory flavors, and fruit flavors.
In the petroleum industry, it functions as a sulfiding agent and can replace methyl mercaptan as a jet fuel additive. It is also applied in the synthesis of 4-(methylthio)phenol and in alpha-substitution reactions of 2-methylfuran-acrolein for food production.
Additionally, DMDS is used as an artificial flavoring agent, corrosion inhibitor, and as an effective soil fumigant in agriculture, highlighting its versatility across multiple industries.
