Cypenamine

Cypenamine (INN, BAN), or cypenamine hydrochloride (USAN), also known as 2-phenylcyclopentylamine, is a psychostimulant drug which was developed by a group at the William S. Merrell Chemical Company in the 1940s. It is currently known only in scientific research and has never been developed for market use. Cypenamine is currently legal throughout the entire world, and though its chemical structure has a vague similarity to certain controlled stimulants like fencamfamine, it is likely that it is too distant for it to be considered an illicit analogue under the United States Federal Analogue Act of the Controlled Substances Act.
