Dimethyl Disulfide (DMDS), identified by its CAS number 624-92-0, is a significant organosulfur compound utilized across various industrial sectors. Its distinct chemical properties, including its characteristic odor and flammability, necessitate a thorough understanding for safe and effective handling and application. This overview covers the key aspects of DMDS, from its physical and chemical characteristics to its broad applications and essential safety considerations, providing valuable insights for industry professionals. As a key chemical supplier, we offer reliable access to this important compound.

The chemical identity of DMDS is established by its molecular formula, C2H6S2, and its structure as the simplest disulfide. It presents as a light yellow transparent liquid, with a distinct, often described as pungent or garlic-like, odor. A critical parameter for industrial use is its purity, which is typically guaranteed to be 99.50% or higher by reputable manufacturers. This high purity ensures its efficacy in its varied roles, including as a solvent, a chemical intermediate, and an additive in specialized products. The physical properties, such as a melting point of -85°C and a boiling point of 109°C, are important considerations for storage and processing conditions.

DMDS demonstrates remarkable versatility in its applications. It is widely employed as a solvent due to its ability to dissolve various organic compounds. In the agricultural industry, it serves as a crucial intermediate for the synthesis of pesticides, contributing to effective crop protection. The petrochemical sector relies on DMDS as a coking inhibitor in refineries and ethylene cracking furnaces, where it prevents the formation of damaging carbon deposits. Additionally, it functions as an additive for fuels and lubricants, enhancing their performance and stability.

Safety is a paramount concern when handling Dimethyl Disulfide. As a flammable liquid, it must be stored and used away from ignition sources, in well-ventilated areas. Its toxic nature, particularly if inhaled or ingested, requires appropriate personal protective equipment (PPE), including gloves, eye protection, and respiratory protection if ventilation is inadequate. Adherence to Material Safety Data Sheets (MSDS) and proper handling procedures is essential to mitigate risks. We advise all users to consult the SDS for detailed safety information before handling DMDS.

For businesses seeking to procure Dimethyl Disulfide, it is important to partner with reliable suppliers and manufacturers. Companies offering high-purity DMDS with consistent quality assurance and competitive pricing are highly sought after. Engaging with experienced chemical suppliers ensures not only the quality of the product but also provides access to necessary technical support and documentation. When you need to buy DMDS, consider established manufacturers who can guarantee the purity and stability required for your industrial applications.
