What is dimethyl sulfoxide?
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 uses/what is dimethyl sulfoxide used for
The FDA has approved DMSO as a prescription medication for treating symptoms of painful bladder syndrome. It’s also used under medical supervision to treat several other conditions, including shingles. DMSO is easily absorbed by the skin. It’s sometimes used to increase the body’s absorption of other medications.
dimethyl sulfoxide hazards
Contact with the skin may cause stinging and burning and lead to an odor of garlic on the breath. An excellent solvent that can transport toxic solutes through the skin. High vapor concentrations may cause headache, dizziness, and sedation.
dimethyl sulfoxide structure
A 2-carbon sulfoxide in which the sulfur atom has two methyl substituents.In terms of chemical structure, the molecule has idealized Cs 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.
