In focus: 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.
