Descrição geral

Dimethyl sulfoxide (DMSO) is a polar solvent. DMSO activated by electrophile (oxalyl chloride) has been used to oxidize various alcohols (primary, secondary, allylic, benzylic, hindered and bicyclic). Carbonyl compounds are formed as reaction products. It has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction, due to its high stability.

Atenção

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
