General description
Dimethyl Sulfoxide (DMSO) is a polar aprotic solvent that is generally used as a reaction medium and reagent in organic reactions.
Application
Dimethyl Sulfoxide can be used as:
- An oxidant for the conversion of isonitriles into isocyanates.
- A solvent in polymerase chain reaction.
- A cryoprotectant for the preservation of cells, tissues and organs.
- An oxidant in Swern oxidation, that can be activated by oxalyl chloride and used in the oxidation of long-chain alcohols to carbonyls.
- Solvent/oxidant in the α-hydroxylation of ketones in the presence of NBS/I2 catalyst.
