Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound that is a colorless, odorless, and transparent liquid at room temperature. It is a hygroscopic and flammable liquid. Dimethyl sulfoxide has the characteristics of good thermal stability, non protonation, high boiling point, high polarity, and miscibility with water. It is also soluble in most organic compounds such as ethanol, benzene, and chloroform, and is known as the "universal solvent".

Industrial grade dimethyl sulfoxide (DMSO) is mainly used as a reactant in organic chemical synthesis and pharmaceutical intermediate synthesis. DMSO belongs to the fundamental chemical industry and is applied as an organic solvent, reaction medium, and organic synthesis intermediate in fields such as petroleum processing, synthetic fibers, pharmaceuticals, pesticides, electronics, dye coatings, gas separation, synthetic resins, and rare metal wet metallurgy. It is truly a "universal" product. The future development of the dimethyl sulfoxide market will rely more on new application areas, especially in the fields of carbon fiber, electronics, and pharmaceuticals.
