Dimethyl Disulfide (DMDS) is a fascinating and highly useful chemical compound with significant applications across various industries, particularly in petroleum refining and petrochemicals. Understanding its properties, ensuring safe handling, and knowing where to source it reliably are key for any business utilizing this compound. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier of DMDS in China, aims to provide comprehensive information to its partners.

Key Properties and Characteristics of DMDS

DMDS, chemically known as (methyldisulfanyl)methane or simply methyl disulfide, has the molecular formula CH3SSCH3 and the CAS number 624-92-0. It typically appears as a pale yellow liquid with a distinctive, pungent, garlic-like odor, reminiscent of natural gas odorants. This strong odor is a safety feature, making leaks readily detectable. Its key properties include:

  • Assay: High purity, typically 99.5%.
  • Flash Point: Low, around 16°C, classifying it as a flammable liquid.
  • Density: Approximately 1.060-1.065 at 20/4°C.
  • Sulfur Content: High, around 67.9-68.3% by weight, making it an efficient sulfur source.
  • Applications: Primarily used as a catalyst sulfiding agent in refineries, an anti-coking agent in steam crackers, a pesticide intermediate, and sometimes as an industrial solvent.

Its chemical reactivity, particularly the ability to decompose into H2S at elevated temperatures, is central to its industrial utility.

Safe Handling and Storage Practices

Given its flammability and strong odor, proper handling and storage of DMDS are crucial. It should be stored in a cool, dry, well-ventilated area, away from direct sunlight, ignition sources, and incompatible materials such as oxidants and acids. When handling DMDS, appropriate personal protective equipment (PPE) is essential, including chemical-resistant gloves, safety goggles, and respiratory protection if ventilation is inadequate. Grounding containers during transfer is also recommended to prevent static discharge. As a trusted supplier, we provide detailed safety data sheets (SDS) with every shipment to guide safe usage.
