Dimethylsulfoxide (abbreviated as DMSO) is a sulfur-containing organic compound, with the English name Dimethylsulfoxide and the molecular formula (CH3)2SO. At room temperature, it is a colorless, odorless, transparent liquid with hygroscopicity and is flammable. It has the characteristics of high polarity, high boiling point, non-protonic, and miscibility in water. It has extremely low toxicity and good thermal stability. It does not mix with alkanes and is soluble in most organic substances such as water, ethanol, propanol, ether, benzene and chloroform. It is hailed as the "universal solvent". It is the one with the strongest dissolving power among the commonly used organic solvents. It can dissolve most organic substances, including carbohydrates, polymers, peptides, as well as many inorganic salts and gases. It can dissolve solute equivalent to 50-60% of its own weight (other common solvents can only dissolve 10-20%), so it is very important in sample management and high-speed drug screening. Under certain conditions, when dimethyl sulfoxide comes into contact with acyl chloride, an explosive reaction will occur.
It is used as an analytical reagent and a stationary liquid for gas chromatography. It is also used as a solvent in ultraviolet spectroscopy analysis, as a reaction medium for aromatic hydrocarbon extraction, resins and dyes, and as a solvent for acrylic fiber polymerization and spinning, etc. It can be used as an organic solvent, reaction medium and intermediate in organic synthesis. Extremely wide. This product has a very high selective extraction capacity and is used as a polymerization and condensation solvent for acrylic resins and polysulfone resins, a polymerization and spinning solvent for polyacrylonitrile and acetate fibers, an extraction solvent for the separation of alkanes and aromatics, a reaction medium for the extraction of aromatics and butadiene, acrylic fiber spinning, plastic solvents, organic synthetic dyes, pharmaceuticals and other industries. In the field of Chemicalbook medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects and a strong penetrating power for the skin. Therefore, it can dissolve certain drugs, allowing these drugs to penetrate the human body and achieve therapeutic purposes. Taking advantage of this carrier property of dimethyl sulfoxide, it can also be used as an additive in pesticides. Adding a small amount of dimethyl sulfoxide to some pesticides helps the pesticides penetrate into plants, thereby enhancing their efficacy. Dimethyl sulfoxide can also be used as a dyeing solvent, decolorizing agent, and dyeing carrier for synthetic fibers. It can also serve as an absorbent for recovering acetylene and sulfur dioxide, a modifier for synthetic fibers, an antifreeze, as well as a dielectric for capacitors, brake fluid, and an extractant for rare metals, etc.
GRAS(FEMA). Studies have shown that dimethyl sulfoxide (DMSO) has severe toxic effects, interacting with hydrophobic protein groups to cause protein denaturation, and it has vascular toxicity and liver and kidney toxicity. DMSO is a highly toxic substance. When using it, be sure to avoid its evaporation. Prepare 1% to 5% ammonia water as a backup. If it gets on the skin, wash it thoroughly with plenty of water and dilute ammonia water. The most common side effects are nausea, vomiting, rash and the smell of garlic, onion and oyster in the skin and exhaled breath.
