DMSO is an unusually nontoxic organic solvent that is finding increased use in pharmaceutical synthesis, the manufacture of electronics, and drug delivery in the body. Its use is supported by over 50 years of industrial and academic experience. Reproductive and Developmental Toxicity. A great number of toxicological, environmental and medical studies have been performed with DMSO to determine the safety of this chemical.

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. In terms of chemical structure, the molecule has idealized C s symmetry. It has a trigonal pyramidal molecular geometry consistent with other three-coordinate S IV compounds,  with a nonbonded electron pair on the approximately tetrahedral sulfur atom. It was first synthesized in by the Russian scientist Alexander Zaytsev , who reported his findings in The sulfur center in DMSO is nucleophilic toward soft electrophiles and the oxygen is nucleophilic toward hard electrophiles.
DMSO Health & Safety
AS with many other unproved substances with seemingly miraculous properties, DMSO has been dubbed alternately a panacea and a snake oil. The drug has also attracted a considerable cult following, enormous journalistic attention and highly profitable sales for unapproved uses. The Food and Drug Administration has approved DMSO for only one medical use: to relieve the pain of a rare bladder disorder called interstitial cystitis. However, since DMSO is legally sold over the counter as an industrial chemical as well as by veterinarian's prescription for a few animal problems , the Federal Government cannot stop people from buying and applying it for myriad conditions ranging in seriousness from sprained ankles to cancer.
The story of dimethyl sulfoxide DMSO is an unusual one. This by-product of the paper making process was discovered in Germany in the late 19th century. Scientists discovered that they could use DMSO as a transportation device to pass small molecules through skin. Since then, scientists have researched the potential benefits and risks of using DMSO to treat a variety of conditions.
