Commercial Information
Storage & Shipping
Storage Conditions
Store tightly closed in a dry, cool, well-ventilated flammable-liquid area. Keep away from heat, sparks, flames and incompatible oxidizing agents; restrict access to trained personnel.
Packaging Integrity
Inspect drum seals and compatible transfer connections before unloading. Maintain clear lot identification, check for leakage, and keep sampling and transfer equipment dedicated to sulfur chemicals.
Packaging
Drums / IBC / ISO tank
Handling & Protection
Use closed transfer and effective local exhaust. Bond and ground conductive equipment and control ignition sources. Wear suitable chemical-resistant gloves, eye protection and antistatic protective clothing; avoid vapor exposure and splashes.
What Is Dimethyl Disulfide (DMDS)?
Dimethyl disulfide (DMDS), CAS 624-92-0, C2H6S2, molecular weight 94.20 g/mol, contains about 68% sulfur. It is a widely used sulfiding agent for activating hydrotreating, hydrodesulfurization and hydrocracking catalysts, and an intermediate for sulfur-containing chemicals.
The supply specification sets purity ≥99.8%, sulfur ≥68%, water ≤0.05% and methyl mercaptan ≤0.01%. It has a strong odour, so closed handling and odour control are needed.
DMDS ships as UN 2381, Class 3 with subsidiary Class 6.1, packing group II, and is environmentally hazardous in bulk. Sulfur addition follows the catalyst supplier and unit procedure.
As a dimethyl disulfide supplier and exporter in China, ZXCHEM ships DMDS in drums, IBCs or ISO tanks.
