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.

The chemical process formerly used in Bogalusa to manufacture DMSO and dimethyl sulfide (DMS) was unique in that it ultimately relied on biorenewable inputs. Original Gaylord DMS process: 1961-2010 The old Gaylord plant received a portion of the Kraft black liquor generated by the Temple Inland paper mill, which was used as a sulfur alkylating ...

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]
