It is mainly used in the production of quaternary ammonium compounds for textile auxiliaries and quaternary ammonium salts of dyes. It is also a catalyst and acid neutralizer for condensation reactions and is useful as an intermediate for manufacturing medicines, pesticides and other chemicals.

Triethylamine is the active ingredient in FlyNap, a product for anesthetizing Drosophila melanogaster. It is used in mosquito and vector control labs to anesthetize mosquitoes. This is done to preserve any viral material that might be present during species identification.

The bicarbonate salt of triethylamine (often abbreviated TEAB) is useful in reverse phase chromatography, often in a gradient to purify nucleotides and other biomolecules.
