N-Phenethyl-4-piperidinone (NPP) is a derivative of 4-piperidinone with the molecular formula C₁₃H₁₇NO. It is used as an intermediate in the manufacture of chemicals and pharmaceutical drugs such as fentanyl.

Because of its possible use in the illicit manufacture of fentanyl, the United States Drug Enforcement Administration (DEA) placed NPP under control as a List 1 Chemical in 2007. Both domestic sales and domestic importations are thus subject to DEA reporting requirements.^[3]
