Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O. 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.
Deuterated DMSO, also known as dimethyl sulfoxide-d 6, is an isotopologue of dimethyl sulfoxide (DMSO, (CH 3) 2 S=O)) with chemical formula ((CD 3) 2 S=O) in which the hydrogen atoms ("H") are replaced with their isotope deuterium ("D"). Deuterated DMSO is a common solvent used in NMR spectroscopy.

For example, dimethyl sulfide is oxidized to dimethyl sulfoxide and then further to dimethyl sulfone. Unsymmetrical sulfides are prochiral, thus their oxidation gives chiral sulfoxides. This process can be performed enantioselectively. [9] [10] Symmetrical sulfoxides can be formed from a diorganylzinc compound and liquid sulfur dioxide. [11]
The most common sulfoxide ligand is dimethyl sulfoxide (dmso). Many sulfoxides are known because an enormous range of organic substituents are possible. When the two substituents differ, the ligand is chiral. Chiral sulfoxides are configurationally stable. One example is methyl phenyl sulfoxide.
Dimethyl sulfide (DMS) or methylthiomethane is an organosulfur compound with the formula (CH 3) 2 S. It is the simplest thioether and has a characteristic disagreeable odor. It is a flammable liquid that boils at 37 °C (99 °F).
