Dimethyl disulfide, an organic compound with the formula C2H6S2, is a notable organosulfur compound. It is known by various names, including methyl disulfide, 1,2-dimethyldisulfan, and 2,3-dithiabutane, characterized by its S-S (disulfide) bond. Its CAS registration number is 624-92-0.
Primarily, dimethyl disulfide serves as a sulfidizing agent for hydrogenated desulfurization catalysts in fuel oil refining. It is also utilized as an intermediate in agricultural chemicals, a solvent in synthetic resin production, and a thiomethylating agent. Additionally, it finds use in instrumental analysis and solution preparation at the research level. Despite its pungent sulfur odor, reminiscent of garlic, it is employed as a flavoring agent in foods like onions and cabbage, where it can contribute to the unwanted odor during cooking.
This compound has a molecular weight of 94.19, melts at -85°C, and boils at 110°C. It appears as a clear yellow liquid at room temperature, with a distinctive sulfur-garlic odor. Its density is 1.06 g/mL, and it dissolves well in organic solvents like ethanol and ether while being slightly soluble in water.
Available primarily for research and development, dimethyl disulfide is marketed in various volumes, including 5mL, 25mL, 250mL, and 1L. It is intended for use in organic synthesis and standard solution preparation for instrumental analysis, not beyond research purposes.
The synthesis of dimethyl disulfide can be achieved through the reaction of methyl iodide with potassium disulfide or by methanethiol oxidation with iodine. Naturally, it is present in certain fishes, cruciferous plants, and garlic, and is produced during the decomposition of organic waste, including garbage and sewage.
As a flammable substance with a flash point of 15°C, dimethyl disulfide can ignite from heat, sparks, or flames. It reacts violently with strong oxidizers, bases, and reducing agents, producing hazardous combustion by-products such as carbon monoxide, dioxide, and sulfur oxides. Its chlorination and oxidation processes yield various sulfur-containing compounds.
Given its flammability and potential health hazards, dimethyl disulfide is regulated under various safety laws. It poses risks of acute toxicity, skin and eye irritation, and potential long-term health effects. Proper handling, per occupational health and safety regulations, is essential to mitigate these risks.
