DMDS Applications
Refinery Catalyst Sulfiding
Dimethyl disulfide is used as a sulfiding agent for catalyst activation and presulfiding in refinery hydrotreating and hydrodesulfurization processes.
For refinery procurement, assess the purity and impurity specifications against the requirements of your process and catalyst supplier.
Chemical Intermediate Applications
DMDS is also used as an intermediate in chemical manufacturing, including certain agrochemical production processes.
To evaluate suitability, provide your intended application, required quality limits and testing criteria when requesting product information.

Frequently Asked Questions
Are DMDS and dimethyl disulfide the same chemical?
Yes. DMDS is the abbreviation for dimethyl disulfide. Its CAS number is 624-92-0.
What purity do you guarantee?
Our product specification is 99.5% minimum purity. The reference test table shows a result of 99.9%, but that result is not the guaranteed minimum for every shipment.
Which impurity limits are included in the specification?
The listed limits are methyl mercaptan at a maximum of 0.01% and moisture at a maximum of 0.06%. Please send any additional acceptance criteria for review.
What is the minimum order quantity?
MOQ is confirmed according to packaging and shipment arrangements. Send your required quantity and destination to receive a quotation.
Can I request a sample?
Contact us with your testing requirements and delivery location. Sample availability and shipping arrangements will be confirmed before dispatch.
What is the delivery lead time?
Lead time depends on stock, order quantity, packaging and transport arrangements. Request a confirmed dispatch schedule with your quotation.
What payment terms are available?
Payment terms are agreed upon in the quotation and sales contract. Include your preferred terms when submitting an inquiry.
How can I obtain the COA, SDS and export documents?
List the documents required for your purchasing and import process when requesting a quotation. Our team will confirm document availability and shipment-specific requirements before order confirmation.
