Chemical Description

  • Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high boiling point. DMSO has the unusual property that many individuals perceive a garlic-like taste in the mouth after DMSO makes contact with their skin.
  • Dimethyl sulfoxide is widely used as a solvent and reaction reagentIt can also be used as a dyeing solvent, de-dyeing agent, dyeing carrier for synthetic fibers, and an absorbent for recovering acetylene and sulfur dioxide.
  • Dimethyl sulfoxide is a transparent liquid containing sulfur compounds. It is widely used in the fields of petroleum, chemical industry, metallurgy, electronics, coatings.
  • Dimethyl sulfoxide (abbreviated DMSO) is a sulfur-containing organic compound; molecule formula: (CH3) 2SO; It exhibits as colorless, odorless, hygroscopic and flammable transparent liquid at room temperature. It has both high polarity as well as high-boiling point. It also has aprotic and water-miscible characteristics.
  • It has low toxicity, good thermal stability, and is not miscible with paraffin. It is soluble in water, ethanol, propanol, ether, benzene and chloroform and many other kinds of organic substance and is called the "universal solvent." It is a common organic solvent which has the strongest dissolving ability. It can dissolve most organic compounds including carbohydrates, polymers, peptides, as well as many inorganic salts and gas. It can dissolve a certain amount of solute whose weight is equal to 50-60% of itself (other common solvents usually only dissolve 10-20%), so it is very important in the sample management as well as high-speed screening of drugs. Under certain conditions, contact between dimethyl sulfoxide and chloride can even lead to explosive reactions.
  • dimethyl sulfoxide is widely used as solvents and reagents, particularly as the processing reagent and spinning solvent at the reaction of acrylonitrile polymerization used for polyurethane synthesis and the spinning solvent. It can also be used as the synthetic solvent for polyamide, polyimide and polysulfone resin as well as the extraction solvents for aromatic hydrocarbon and butadiene extraction solvents and solvents for synthesizing chloro fluoro aniline.
  • In addition, dimethyl sulfoxide can also be directly used as the raw material or carrier of some drug in the pharmaceutical industry. dimethyl sulfoxide itself has various effects such as anti-inflammatory, analgesic, diuretic, and sedative, and thus also being known as "panacea" which is usually as the active ingredient of analgesic medication being added to the drug.
