para-Chlorophenylpiperazine (pCPP) is a psychoactive drug of the phenylpiperazine class.[1] It is relatively obscure, with limited human use, and produces slightly psychedelic effects.[citation needed] It has been encountered in illicit capsules as a recreational drug similarly to other piperazines like mCPP.[1] Scientific research has demonstrated pCPP to have serotonergic effects, likely acting as a non-selective serotonin receptor agonist and/or releasing agent.[2][3]
A known use has been in the synthesis of L-745,870.
