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.
vapor pressure at 20 °C = 0.556 mbar = 0.417 mmHg [2] log 10 of dimethyl sulfoxide vapor pressure. ... 0.0034 % −1 cm −1 in unpHed water at 260 nm IR; Spectrum:
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 following compounds are liquid at room temperature and are completely miscible with water; ... 2 SO: dimethyl sulfoxide: 67-68-5 C 4 H 8 O 2: 1,4-Dioxane: 123-91 ...

Dichlorotetrakis(dimethyl sulfoxide) ruthenium(II) describes coordination compounds with the formula RuCl 2 (dmso) 4, where DMSO is dimethylsulfoxide. Both cis and trans isomers are known, but the cis isomer is more common. The cis isomer is a yellow, air-stable solid that is soluble in some organic solvents.
It is iodide salt of a common sulfoxonium ions. This compound, a colorless solid, is commercially available. It may be prepared by the alkylation of dimethyl sulfoxide with iodomethane: [1] (CH 3) 2 SO + CH 3 I → (CH 3) 3 SO + I −. The trimethylsulfoxonium ion features a tetrahedral sulfur center. The ion has idealized C 3v symmetry.
DMSO reductase is a molybdenum-containing enzyme that catalyzes reduction of dimethyl sulfoxide (DMSO) to dimethyl sulfide (DMS). This enzyme serves as the terminal reductase under anaerobic conditions in some bacteria, with DMSO being the terminal electron acceptor. During the course of the reaction, the oxygen atom in DMSO is transferred to ...
