Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound, the molecular formula is (CH3)2SO, at room temperature is colorless odorless transparent liquid, is a hygroscopic flammable liquid. With high polarity, high boiling point, good thermal stability, aprotic, and water miscible characteristics, can dissolve in ethanol, propanol, benzene and chloroform and other most organic matter, known as "universal solvent".
Dimethyl sulfoxide is widely used as solvent and reaction reagent, especially in organic synthesis, medicine, electronics and other important applications.
1, solvent and reaction medium: dimethyl sulfoxide is an important aprotic polar solvent, able to dissolve a variety of organic and inorganic compounds. Especially in acrylonitrile polymerization, polyurethane synthesis and wire drawing, polyamide, polyimide and polysulfone resin synthesis.
2, medical applications: it can be directly used as a raw material and carrier of some drugs, because it has anti-inflammatory analgesic, diuretic, sedation and other effects. It can also enhance the permeability of drugs, and can also be used for freezing cells, because it can reduce the freezing point of cells and reduce the formation of ice crystals, thereby reducing the damage to cells from freezing.
3, antifreeze: automotive antifreeze, brake oil, hydraulic fluid and other products of the ideal component. Dso antifreeze is especially useful in cold areas because it can be replenished with snow instead of water at any time.
4. Analytical reagent: dimethyl sulfoxide is used as an analytical reagent and a stationary liquid for gas chromatography, and is also used as a solvent for ultraviolet spectral analysis.
5, pesticide additives: dimethyl sulfoxide can be used as an additive to pesticides, because it helps the pesticide to penetrate into the plant, thereby improving the efficacy.
Other uses: dimethyl sulphone can also be used as a synthetic fiber dyeing solvent, dye remover, dyeing carrier, and recovery of acetylene, sulfur dioxide absorbent, synthetic fiber modifier, antifreeze and capacitive media, brake oil, rare metal extraction agent.
Although DSO is widely used, it also has certain toxic effects, such as vascular toxicity and hepatorenal toxicity. Therefore, it is necessary to pay attention to safety when using dimethyl sulfoxide and avoid unnecessary contact and inhalation.

Product introduction
1. Colorless liquid, flammable, almost odorless, with bitter taste. The product is a highly polar organic solvent, can be mixed with water in any proportion, in addition to petroleum ether, can dissolve general organic solvents. At 20ºC can absorb hydrogen chloride 30%(weight); Nitrogen dioxide 30%(weight); Sulfur dioxide 65%(weight). Strong hygroscopic, at 20 ° C, when the relative humidity is 60%, it can absorb 70% of its own weight from the air. The product is a weak oxidizing agent, and the non-aqueous dimethyl sulfoxide is non-corrosive to metals. To iron when hydrated; Metals such as copper are corrosive, but not aluminum. Stable to alkali. Heating in the presence of acid produces a small amount of methyl mercaptan; Formaldehyde; Dimethyl sulfur; Mesylate and other compounds. There is decomposition phenomenon at high temperature, and it can react violently in the case of chlorine, burning in the air and emitting a light blue flame.Chemical properties: Reduction of dimethyl sulfoxide to methyl sulfide. Oxidized to dimethyl sulfone by strong oxidant;2. When dimethyl sulfoxide is in contact with acyl chloride such as cyanuryl chloride, benzoyl chloride, acetyl chloride, benzoyl iodide chloride, thionyl chloride, thionyl chloride, phosphorus trichloride, etc., intense exothermic decomposition reaction occurs. It combines with nitric acid to form (CH3)2SO·NHO3. Dimethyl sulfoxide can be regenerated by interaction with barium carbonate. React with concentrated hydroiodic acid to form dimethyl sulfur compound.
3. Dimethyl sulfoxide has water absorption and needs to be dried before use.
Industrial use
1, used for aromatic extraction, resin and dye reaction medium, acrylic fiber polymerization, drawing solvent, etc
2, can be used as organic solvent, reaction medium and organic synthesis intermediates. Extremely versatile. This product has high selective extraction ability. In medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects, and has strong permeability to the skin, so it can dissolve some drugs, so that such drugs can penetrate into the human body to achieve therapeutic purposes. It can also be used as an additive to pesticides.
3, used as an analytical reagent and gas chromatography fixed liquid, but also used as a solvent in ultraviolet spectral analysis
4, transdermal accelerator. Dimethyl sulfoxide (DSO) is one of the earliest transdermal osmotic accelerators, which may be related to its solvent properties.
5. Antifreeze. Automotive antifreeze, brake oil, hydraulic fluid components provide convenience. Dimethyl sulfoxide is also used in deicing agents, coatings, anti-freeze of various latex, gasoline, aviation antifreeze, bone marrow, blood, organ low temperature preservation of antifreeze.
