General description
Dimethyl sulfoxide is an organosulfur, commonly used as a polar solvent that can dissolve a wide range of polar and non-polar compounds. It is also utilized as a reaction reagent in several well-known processes, including swern oxidation, 2a pfitzner-moffatt oxidation, 2b, and the corey-chaykovsky reaction.
