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 has a relatively high melting point. DMSO has the unusual property that many individuals perceive a garlic-like taste in the mouth after contact with the skin.
1. Pharmaceutical grade DMSO demonstrates a range of pharmacological activity including analgesia and anti-inflammation. Due to its ability to penetrate biological membranes, it is used as a vehicle for the transdermal delivery of active pharmaceuticals. It is also used to protect tissue during cryopreservation
2. Its use as a solvent, both in organic synthesis and industrial applications (polymer chemistry, pharmaceuticals and agrochemicals)
3. DMSO also makes a very good paint stripper as it is able to remove many paints from both wood and metal in a small amount of time
