Dimethyl Sulfoxide (DMSO) - Common Organic Chemistry

The high dissolving power of DMSO makes deuterated DMSO (DMSO-d6) a common solvent for NMR. One of the major drawbacks of DMSO is the difficulty of removal after a reaction. Its high boiling point (189 C) makes removal by rotovap very difficult. DMSO is also used as a reagent in a variety of different reactions. Common Uses:
