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.
An investigation by Lawrence Livermore National Laboratory suggested that Ramirez had been self-administering dimethyl sulfoxide (DMSO) as a pain treatment. The oxygen from the mask provided by paramedics during her transport to the hospital likely converted the DMSO into dimethyl sulfate (DMS), a highly toxic and carcinogenic alkylating agent.
Paint strippers come in a liquid, or a gel ("thixotropic") form that clings even to vertical surfaces. Solvent strippers may also have formulations with limonene (obtained from orange peels) (or other terpene solvents). Nitromethane is another commonly used solvent. Dimethyl sulfoxide is a less toxic alternative solvent used in some ...
Being weakly basic, sulfoxide ligands are generally labile, i.e. they are rapidly displaced by other more basic ligands. O-bonded sulfoxide ligands are susceptible to oxidation at sulfur. In this way, the weakly bonded ligand is converted into a leaving group, such as dimethylsulfone. Since dmso is susceptible to deprotonation by strong base ...
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...
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]
