Description

Dimethyl Disulfide (DMDS) is a versatile organosulfur compound widely used as a key intermediate and specialty chemical in various industrial processes. Its primary value lies in its role as a sulfiding agent and a source of sulfur in petrochemical refining and agrochemical synthesis. This product is essential for manufacturers in the petroleum, agricultural, and chemical synthesis sectors seeking reliable, high-purity sulfur reagents.

Application

• Petrochemical Catalyst Presulfiding: Used as a sulfiding agent to activate hydrotreating and hydrocracking catalysts in refineries, improving their activity and longevity.
• Agrochemical Intermediate: Serves as a crucial building block in the synthesis of pesticides, fungicides, and soil fumigants.
• Flavor and Fragrance Industry: Employed as a precursor for sulfur-containing flavor compounds, contributing to savory notes in food products.
• Chemical Synthesis: Acts as a methylthiolating agent and a versatile reagent in organic synthesis for pharmaceuticals and specialty chemicals.
• Gas Odorant: Used in trace amounts as a stenching agent for natural gas and liquefied petroleum gas (LPG) for leak detection.
• Analytical Chemistry: Utilized as a standard or reagent in various analytical methods.

Quality Control

Our Dimethyl Disulfide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity and consistency. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, identity, and impurity profiles to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature (store under inert atmosphere), it is recommended to keep containers tightly sealed under an inert gas blanket after opening. Recommended storage temperature is 2-25°C.
