Descripción

General description

Formamide is a polar solvent mainly used for resins and plasticizers. It can be prepared by direct synthesis from carbon monoxide and ammonia.

Application

Formamide can be used as a solvent:

• To synthesize tetrakis(trialkylsilyl) diphosphate by reacting disodium dihydrogen diphosphate with trialkyl chlorosilane.
• In Cu/C catalyzed cycloaddition between azides and terminal alkynes to synthesize triazoles.

La formamida desestabiliza los dúplex de ácidos nucleicos y puede utilizarse, normalmente, a una concentración del 50 % en protocolos de hibridación que requieran temperaturas de hibridación mas bajas.
