Wiktionary
- n. organic chemistry An alicyclic heterocycle, containing 5 carbon atoms and one nitrogen atom, formally derived by the hydrogenation of pyridine; many of its derivatives are alkaloids or pharmaceuticals

Examples
“The fourth and final group of addictive substances includes anabolic androgenic steroids (AAS); inhalants like nitrous oxide, amyl nitrate, and solvents; phenyl cyclohexyl piperidine (PCP), which is also known as “Angel Dust”; and Ketamine.”
“Phenyl cyclohexyl piperidine, better known as PCP or “Angel Dust,” was originally developed as a surgical anesthetic for use with humans.”
“Lipids, sterols and a piperidine alkaloid from Prosopis spigigera leaves.”
“Prof. Filehne, of Erlangen, who has studied a large number of these pyridine and quinoline derivatives, found, moreover, that the hydrochlorate of ethyl-piperidine had a physiological action quite analogous to that of conine.”
“_Piperine_ has also been made by the uniting of piperidine and piperic acid, and, as piperidine has already been formed from pyridine, we have here a true synthesis also.”
“The formula of conine, C_ {8} H_ {17} N, shows it to be homologous with piperidine, C_ {5} H_ {11} N, a derivative of piperine, the alkaloid of pepper, to be spoken of later; and, just as piperidine is derived from pyridine by the action of reducing agents, so conine is probably derived from a propyl-pyridine.”
“The relationship between these and piperidine is seen in the following formulæ:”
“If we introduce six hydrogen atoms into pyridine, we convert it into piperidine.”
“Pentamethylinediamine is the principal intermediary product, and this gives piperidine when distilled with superheated steam.”
“He at first supposed that this alkaloid was piperidine in which two hydrogen atoms were replaced by the isopropyl radical (C_ {3} H_ {7}), its formula being taken as”
