Application

Triethylamine has been used:
  • as a hydrogen donor for the polymerization of various monomers[1]
  • to catalyze silanization[2]
  • in the synthesis of the Cy3-Alexa647 heterodimer[3]
  • in the synthesis of methacrylated solubilized decellularized cartilage[4]

Biochem/physiol Actions

Triethylamine is known to drive polymerization reaction. It acts as a source of carbon and nitrogen for bacterial cultures. Triethylamine is used in pesticides.[5] Triethylamine can serve as an organic solvent.[6]
