Dimethyl sulfoxide

Dimethyl sulfoxide

Popularly knowns by its acronym DMSO, is an organosulfur compound. It  is an aprotic polar solvent, a mild oxidant, and a common ligand in co-ordination chemistry. Its versatility lies in the fact that it can dissolve polar as well as non-polar solutes and hence it is a special solvent in organic syntheses. Its utility is further due to its low cost, low toxicity, and stability.

It is manufactured by oxidation of dimethyl sulfide by either oxygen or nitrogen dioxide.
