Application

Tetraethylammonium bicarbonate is used:
  • In the synthesis of carbamate esters from amines.
  • As a precipitant for synthesizing Cu/ZnO catalysts via coprecipitation method.
  • As an alternative to the traditional phase-transfer system in [18F]radiofluorinations for preventing microreactor blockages.
  • To promote carboxylation of secondary carboxamides bearing a leaving group at the α-position in the synthesis of oxazolidine-2,4-diones.
