Description générale

Dimethyl Sulfoxide is an apolar protic solvent that is generally used as a reaction medium and reagent in organic reactions.

Application

Dimethyl Sulfoxide may be used as an oxidant for the conversion of isonitriles into isocyanates. DMSO activated by oxalyl chloride can be used in the oxidation of long-chain alcohols to carbonyls.
