ortho-Methoxyphenylpiperazine (oMeOPP), also known as 2-methoxyphenylpiperazine (2-MeOPP), is a phenylpiperazine derivative which is known to act as a serotonergic agent. Along with various other phenylpiperazines, like benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP), oMeOPP has been found in illicit drug samples.
