Description

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.

Formamide destabilizes nucleic acid duplexes and may be used, typically, at a concentration of 50%, in hybridization protocols requiring lower hybridization temperatures.
