Dimethyl sulfoxide
(
DMSO
) is an organosulfur compound with the formula (CH
3
)
2
SO. 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 boiling 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.
DMSO is also a osmotic protective agent that can reduce the freezing point of cells, reduce the formation of ice crystals, the damage of free radicals to cells, and change the permeability of biofilms to electrolytes, drugs, poisons and metabolites.
