Triacetone amine is the heterocycle that arises via the condensation of acetone and ammonia according to the following equation:

3 CH₃C(O)CH₃ + NH₃ → OC(CH₂C(CH₃)₂)₂NH + 2 H₂O

It is primarily used as a light stabilizer for plastics 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,^[1] as well as the radical oxidizer 4-Hydroxy-TEMPO.^[2]
