What is Piperidine?
Piperidine is an azacycloalkane that is cyclohexane in which one of the carbons is replaced by a nitrogen. It is a metabolite of cadaverine, a polyamine found in the human intestine. It has a role as a base, a reagent, a catalyst, a non-polar solvent, a protic solvent, a plant metabolite and a human metabolite. It is a member of piperidines, a secondary amine, a saturated organic heteromonocyclic parent and an azacycloalkane. It is a conjugate base of a piperidinium.
