what is dimethyl sulfoxide
Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH3) 2 S O.This colorless liquid 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.It has a relatively high melting point.llustrative is the complex dichlorotetrakis(dimethyl sulfoxide)ruthenium(II) (RuCl 2 (dmso) 4). In this complex, three DMSO ligands are bonded to ruthenium through sulfur. The fourth DMSO is bonded through oxygen. In general, the oxygen-bonded mode is more common.
