Dimethyl Disulfide CAS#624-92-0

Dimethyl disulfide (DMDS) is an industrial‑grade chemical featuring a minimum purity of 99%. This flammable yellow‑colored liquid emits a distinctive sulfur‑like odour.

Its major physical‑chemical parameters are listed as follows: melting point at ‑84.7°C, boiling point at 109.6°C, vapour pressure of 3.0×10⁶ mPa under 20°C condition, relative density of 1.062 (20°C), and freezing point of 16°C. It displays poor water solubility of 2.7 g/L at 20°C, yet can blend freely with the majority of organic solvents within 15‑25°C temperature range.

Dimethyl disulfide maintains thermal stability below 300 °C. Nevertheless, it will turn unstable when exposed to oxidizing substances, a property that renders it applicable for multiple industrial‑scenario usages.

Dimethyl disulfide (DMDS) finds extensive application as a chemical intermediate and food additive for items including onion, garlic, cheese, meat products, soups, savoury flavour formulations and fruit‑based flavours.

Within the petroleum sector, it acts as a sulfiding agent and serves as an alternative to methyl mercaptan for jet fuel additive applications. Moreover, it participates in the synthesis of 4‑(methylthio)phenol, as well as alpha‑substitution reactions involving 2‑methylfuran‑acrolein for food‑grade manufacturing processes.

Beyond the above‑mentioned uses, DMDS also functions as an artificial flavouring substance, corrosion inhibitor and potent soil fumigant for agricultural purposes, demonstrating its broad applicability across diverse industrial fields.
