Product Properties
Dimethyl sulfide is a volatile liquid with a characteristic sulfur odor. Its typical boiling point is approximately 37.3°C, and its relative density is approximately 0.85, with water taken as 1.
DMS has limited solubility in water and is soluble in various organic solvents. Its volatility and flammability require suitable closed handling systems, compatible packaging and controlled storage conditions.
Physical property values are provided for general product identification. Refer to the current product Safety Data Sheet for handling and storage information.
Dimethyl Sulfide Applications
Steam Cracking and Petrochemical Processing
DMS is used as a sulfur-containing additive in suitable steam cracking processes. It supports the passivation of active metal surfaces in furnace coils, helping control catalytic coke formation and associated carbon monoxide production.
Its suitability depends on the feedstock, furnace metallurgy, operating conditions and the plant’s sulfur management requirements. Product selection should follow the process licensor’s or plant engineering team’s specifications.
Organic Synthesis and Chemical Intermediates
Dimethyl sulfide is a raw material for producing dimethyl sulfoxide (DMSO) and other sulfur-containing compounds. It is also used as a reagent in selected organic synthesis routes.
For these applications, buyers should review not only DMS purity but also moisture and impurity limits against their process requirements.

Storage and Handling
Dimethyl sulfide is a highly flammable liquid. Store it in a cool, well-ventilated area designed for flammable chemicals, away from heat, sparks, open flames and strong oxidizing agents.
Keep containers tightly closed and use compatible handling equipment. Grounding, bonding and appropriate explosion-protected equipment are required where applicable to control ignition risks.
Personnel should follow the current product SDS and site procedures for storage, transfer and emergency response. Storage temperature and any inert-gas requirements should be confirmed for the supplied product and storage installation.
Frequently Asked Questions
What purity of dimethyl sulfide do you supply?
Our stated specification is a minimum DMS purity of 99.50%. Please provide any additional impurity limits required by your process.
Is DMS the same as DMDS?
No. Dimethyl sulfide (DMS) has the molecular formula C₂H₆S, while dimethyl disulfide (DMDS) has the formula C₂H₆S₂. Their physical properties and process requirements differ, so substitution requires technical review.
What packaging is available?
Packaging options include 200 L steel drums and ISO tanks. Final packaging and loading details are confirmed according to the order and transport requirements.
What is the MOQ?
The minimum order is one container. Net shipment weight depends on the selected packaging and loading arrangement.
How can I get a price?
Send us your required quantity, specifications, packaging preference and destination port. We will prepare a quotation based on your requirements.
