The crude dimethyl sulfide product was purified by distillation and could then be used to produce DMSO. When Gaylord closed its Bogalusa plant in 2010, it changed its process technology to manufacture DMS from methanol and hydrogen sulfide gas via gas phase thioetherification. This is the dominant method used worldwide to make DMS and there are ...
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.

Dimethyl sulfide has a characteristic odor commonly described as cabbage-like.It becomes highly disagreeable at even quite low concentrations. Some reports claim that DMS has a low olfactory threshold that varies from 0.02 to 0.1 ppm [clarification needed] between different persons, but it has been suggested that the odor attributed to dimethyl sulfide may in fact be due to disulfides ...
Dimethyl sulfoxide (DMSO) is also regarded as a conventional cryoprotectant. Glycerol and DMSO have been used for decades by cryobiologists to reduce ice formation in sperm, [3] oocytes, [4] and embryos that are cold-preserved in liquid nitrogen.
