4-Piperidone is an organic compound with the molecular formula OC(CH2)4NH. It can be viewed as a derivative of piperidine. 4-Piperidone is used as an intermediate in the manufacture of chemicals and pharmaceutical drugs. Substituted and dehydro derivatives of 4-piperidinone are intermediates in alkaloid syntheses.[1]

It is a List I chemical in the United States. It is a precursor to fentanyl.

The N-protonated derivative is typically isolated as the hydrate (HO)2C(CH2)4NH+2.[2]
