Triacetone amine is the heterocycle that arises via the condensation of acetone and ammonia, with phorone being a likely intermediate.

It is primarily used as a stabilizer for plastics, typically via its conversion to number of hindered amine light stabilizers, but also finds use as a chemical feedstock. It is used to prepare the hindered amine 2,2,6,6-tetramethylpiperidine, CH₂[CH₂C(CH₃)₂]₂NH, as well as the radical oxidizer 4-Hydroxy-TEMPO.
