Primary Applications of Dimethyl Disulfide (DMDS)
Dimethyl Disulfide's unique properties, including its sulfur content, reactivity, and potent odor, make it a valuable compound with applications across several industries:
Sulfiding Agent in Petrochemical Industry:
This is one of its most important applications. DMDS is widely used as a sulfiding agent to activate catalysts (e.g., hydrodesulfurization, hydrocracking catalysts) in refineries. It provides a safer and more efficient alternative to hydrogen sulfide for controlled sulfiding, improving catalyst performance and extending their lifespan.
Chemical Intermediate & Reagent:
DMDS serves as a versatile chemical intermediate and reagent in various organic synthesis reactions. It is a precursor for the production of other organosulfur compounds, pharmaceuticals, agrochemicals, and specialty chemicals. It can be used to introduce methylthio groups into organic molecules.
Fumigant & Pesticide:
In agriculture, DMDS is used as a fumigant to control soil-borne pests, nematodes, and weeds, particularly in certain fruit and vegetable crops. It acts as a broad-spectrum biocide, often used as an alternative to methyl bromide in some regions.
Odorant:
Due to its strong, distinctive odor, DMDS can be used as an odorant in various applications where a warning signal for leaks or presence of other substances is required. It can also be a component in some natural gas odorant blends.
Flavoring Agent:
In extremely low concentrations, DMDS contributes to the characteristic flavor and aroma of certain foods, such as garlic, onion, and some cheeses, acting as a flavoring agent in the food industry.

We strongly advise you to consult and strictly adhere to the SDS for the respective product.
| I. Packaging Solutions | II. Transportation Solutions | III. Storage Solutions |
We utilize various UN (United Nations) certified packaging containers based on the chemical nature, hazard class, and transportation requirements of our products. Common packaging types include, but are not limited to: Steel Drums: Suitable for a wide range of liquid and solid products, especially flammable liquids. Plastic Drums/Jerricans: Primarily used for corrosive liquids like acids and bases, or substances incompatible with metal. Composite Drums: Combine the corrosion resistance of a plastic inner liner with the strength of a steel or fiber outer shell. IBCs (Intermediate Bulk Containers): Often referred to as "Tote Bins" or "Cubic Tanks," these are used for larger volumes of liquid or solid dangerous goods, offering efficient storage and transport solutions. Lined Bags or Fibre Drums: Primarily used for powdered or granular solids. Glass Bottles: Typically used as inner packaging for small quantities of high-purity or specialized chemicals, requiring additional absorbent material and sturdy outer packaging (e.g., wooden crates, fiberboard boxes). Steel Cylinders: Specifically designed and constructed as pressure vessels for the storage and transport of compressed, liquefied, or dissolved gases. Available in various capacities and pressure ratings, they are built to withstand high internal pressures and ensure the safe containment of gaseous substances.

Upon receiving your shipment, please carefully verify the integrity of the packaging and the label information.
| Proper storage is crucial for maintaining product quality and ensuring operational safety. The following are general storage principles: Dedicated Areas: Dangerous chemicals should be stored in designated warehouses or areas that meet safety standards, away from residential zones and densely populated areas. Segregated Storage: Strictly classify and segregate products according to their hazard class to prevent incompatible substances from being stored together and causing dangerous reactions (e.g., acids and bases separated, flammables away from oxidizers). Good Ventilation: Storage areas should maintain good natural or forced ventilation to prevent the accumulation of hazardous gases or vapors. Temperature & Humidity Control: Control the temperature and humidity of the storage environment according to the recommendations in the SDS. Avoid direct sunlight and extreme temperatures. Fire and Explosion Prevention: Storage areas for flammable and explosive products should be equipped with adequate fire-fighting equipment, prohibit open flames, and ensure electrical equipment meets explosion-proof standards. Clear Labeling: All storage containers and areas should have clear, conspicuous hazard labels and warning signs. Spill Response: Storage areas should be equipped with appropriate spill response equipment and materials, and personnel should be familiar with emergency procedures. Regular Inspections: Periodically inspect the integrity of storage containers to ensure no leaks or damage, and verify label information. Away from Food and Drinking Water: Avoid cross-contamination.
