Dimethyl sulfoxide (DMSO) is a kind of organic sulfur compounds, molecular formula for the (CH3) 2 so, room temperature is colorless, transparent liquid with hygroscopicity of flammable liquid, has high polarity, high boiling point, the proton in water miscibility characteristics, good thermal stability, soluble in ethanol, propanol, benzene, and chloroform, the number of organic matter mostly, is known as the "universal solvent".

Dimethyl sulfoxide is widely used as a solvent and reaction reagent, especially of acrylonitrile polymerization processing solvents and reel off raw silk from cocoons, synthesis and spinning solvent polyurethane, polyamide, polyimide and polysulfone resin composite solvent, and aromatic hydrocarbons, butadiene extraction solvents and synthetic chlorine fluoro aniline, etc.In addition, in the pharmaceutical industry, dimethysulfone is also used as the raw material and carrier for certain drugs.Dimethyl sulfoxide itself has anti-inflammatory analgesic, diuresis, calm, and so on, also known as the "panacea", often used as active component of analgesic drugs added in drugs.
