what is chemical Dimethyl sulfoxide?
Dimethyl sulfoxide (DMSO)
CAS NO. 67-68-5
Molecular Formula: C2H6OS
Molecular Weight: 78.13g/mol
Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3)2SO. This colorless liquid 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 penetrates the skin very readily, giving it the unusual property for many individuals of being secreted onto the surface of the tongue after contact with the skin and causing a garlic-like taste in the mouth.
What is DMSO used for?
Dimethyl sulfoxide (DMSO) is an aprotic polar solvent with high selective extraction capabilities. It can be used for the separation of alkanes and aromatic hydrocarbons, the synthesis of polyamides, chlorofluoroanilines, polyimides, and polysulfone resins, and as a solvent for acetylene, aromatic hydrocarbons, sulfur dioxide, and other gases. Dimethyl sulfoxide solution also possesses anti-inflammatory, analgesic, diuretic, and sedative properties. In the pharmaceutical industry, it can be used as a drug raw material and carrier, exhibiting strong skin permeability that facilitates drug delivery. Furthermore, DMSO can be used as a capacitor dielectric, antifreeze, brake fluid, and rare metal extractant.
Safety and Handling
While DMSO is considered to have low toxicity compared to many other solvents, it can cause skin irritation upon contact. Proper safety measures should be taken when handling this chemical, including the use of gloves and protective eyewear.
