General description

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.

Application


  • Modification of gelatin by reaction with 1,6-diisocyanatohexane.: This study focuses on the modification of biopolymers using chemical agents, which could be relevant in contexts where DMSO is used as a reaction solvent ( Bertoldo et al., 2007).

  • Characterization of O-acetyl-(4-O-methylglucurono)xylan isolated from birch and beech.: This research characterizes specific wood-derived xylans, potentially enhancing understanding of such biopolymers when dissolved in DMSO for analytical studies ( Teleman et al., 2002).

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.
