Application

The addition of formamide may enhance the specificity and efficiency of amplification of PCR (polymerase chain reaction). It may be used as an ammonia equivalent for the palladium-catalyzed aminocarbonylation of 1-bromo-3-trifluoromethylbenzene to form 3-(trifluoromethyl)benzamide.
Formamide destabilizes nucleic acid duplexes and may be used, typically, at a concentration of 50%, in hybridization protocols requiring lower hybridization temperatures.
