General description
Application
Dimethyl Sulfoxide can be used as:
- An oxidant for the conversion of isonitriles into isocyanates.[3]
- A solvent in polymerase chain reaction.[4]
- A cryoprotectant for the preservation of cells, tissues and organs.[5]
- An oxidant in Swern oxidation, that can be activated by oxalyl chloride and used in the oxidation of long-chain alcohols to carbonyls.[6]
- Solvent/oxidant in the α-hydroxylation of ketones in the presence of NBS/I2 catalyst.[7]
Caution
Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
