Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound with a molecular formula of C2H6OS. It is a colorless, odorless, transparent liquid at room temperature and a hygroscopic flammable liquid. It has the characteristics of high polarity, high boiling point, good thermal stability, aprotic, and water miscibility. It can be dissolved in most organic substances such as ethanol, propanol, benzene and chloroform, and is known as a "universal solvent". Heating in the presence of acid will produce a small amount of compounds such as methyl mercaptan, formaldehyde, dimethyl sulfide, and methanesulfonic acid. Decomposes at high temperature, reacts violently with chlorine, burns in air and emits a light blue flame. It can be used as organic solvent, reaction medium and organic synthesis intermediate. It can also be used as a dyeing solvent for synthetic fibers, a dye remover, a dyeing carrier, and an absorbent for recovering acetylene and sulfur dioxide.

Dimethyl sulfoxide is an extremely important aprotic polar solvent that is soluble in both water and organic solvents. Widely used as solvent and reaction reagent, it has high selective extraction ability. Dimethyl sulfoxide itself has anti-inflammatory, analgesic, diuretic and sedative effects, and can be directly used as raw material and carrier of certain drugs in the pharmaceutical industry. Known as the "panacea", it is often added to the drug as an active ingredient of analgesic drugs.
1. It is used for the extraction of aromatic hydrocarbons, the reaction medium of resins and dyes, the solvent of acrylic fiber polymerization and spinning, etc.
2. It can be used as organic solvent, reaction medium and organic synthesis intermediate. This product has high selective extraction ability, used as polymerization and condensation solvent for acrylic resin and polysulfone resin, polyacrylonitrile and acetate fiber polymerization spinning solvent, extraction solvent for separation of alkanes and aromatics, used for Aromatic hydrocarbons, butadiene extraction, acrylic fiber spinning, plastic solvents and organic synthetic dyes, pharmaceuticals and other industrial reaction medium. In terms of medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects, and has strong penetration into the skin, so it can dissolve certain drugs, allowing these drugs to penetrate into the human body to achieve therapeutic purposes. Utilizing the carrier properties of dimethyl sulfoxide, it can also be used as a pesticide additive. Adding a small amount of dimethyl sulfoxide to some pesticides can help the pesticides penetrate into the plants to improve the efficacy. Dimethyl sulfoxide can also be used as a dyeing solvent, dye remover, and dyeing carrier for synthetic fibers, as well as an absorbent for recycling acetylene and sulfur dioxide, a synthetic fiber modifier, antifreeze, and capacitor media, brake oil, and rare metal extraction. agent etc.
3. It is used as analytical reagent and stationary liquid of gas chromatography, and also used as solvent in ultraviolet spectrum analysis.
4. Transdermal accelerator. Dimethyl sulfoxide is one of the earliest transdermal penetration enhancers, and its penetration-enhancing properties may be related to its solvent property. Dimethyl sulfoxide can denature proteins in skin keratinocytes; it can destroy the orderly arrangement of lipids in the stratum corneum; it can remove lipids and lipoproteins in the stratum corneum, and enhance the penetration of drugs. When sulfoxide is used, it will cause erythema, blisters and irreversible damage to the skin, which has been banned in the United States. The commonly used concentration is 30%-50%.
5. Antifreeze. The freezing point of pure dimethyl sulfoxide is 18.45°C, and dimethyl sulfoxide containing 40% water will not freeze at -60°C, and dimethyl sulfoxide will release heat when mixed with water and snow. Therefore, it is convenient to make automobile antifreeze fluid, brake fluid, and hydraulic fluid components. Ethylene glycol antifreeze is not applicable at low temperatures exceeding -40°C, and has a lower boiling point than dimethyl sulfoxide, is poisonous, and is prone to air lock. Dimethyl sulfoxide antifreeze is used in automobiles and tanks in the northern severe cold region, and can be replenished with snow instead of water at any time. Dimethyl sulfoxide is also used in deicing agents, paints, various latex antifreezes, gasoline, aviation fuel antifreezes, bone marrow, blood, and organ cryogenic preservation.
