Descripción

General description

Dimethyl sulfoxide (DMSO) is a polar solvent. DMSO activated by various electrophiles (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.

Application

Dimethyl sulfoxide (DMSO) has been used as a solvent in the high-throughput compound screening studies conducted on Mtb (Mycobacterium tuberculosis) H37Rv host cells.

Caution

Fácilmente superenfriado, vuelve a fundir lentamente a temperatura ambiente. Producto solidificado que puede volver a licuarse por calentamiento a temperatura ambiente sin detrimento del producto.
