Dimethyl Disulfide (DMDS)

Dimethyl Disulfide (DMDS) is a high-purity organosulfur compound widely used in petrochemical, refinery, and chemical processing industries. It is a clear to pale yellow liquid with a strong sulfur odor and is valued for its effectiveness as a sulfurizing agent and sulfiding catalyst precursor.

DMDS is primarily used for pre-sulfiding and continuous sulfiding of hydroprocessing catalysts, helping improve catalyst activation and extend operational life in refineries. Its controlled sulfur release, consistent composition, and ease of handling make it a preferred choice over traditional sulfur sources.
