Source-derived summary

Substituted piperazines are a class of chemical compounds based on a piperazine core. Some are used as recreational drugs and some are used in scientific research.

List of substituted piperazines

Benzylpiperazines

Phenylpiperazines

ortho-Substituted

2-Chlorophenylpiperazine (oCPP)

2-Methylphenylpiperazine (oMPP)

2-Methoxyphenylpiperazine (oMeOPP)

Mefeclorazine

Vortioxetine

Enpiprazole is known to produce oCPP as a metabolite. It was initially anticipated to produce oMeOPP as a metabolite, but this proved not to be the case.

meta-Substituted

3-Chlorophenylpiperazine (mCPP)

3-Methoxyphenylpiperazine (mMeOPP)

3-Trifluoromethylphenylpiperazine (TFMPP)

1-(3-Chlorophenyl)-4-(2-phenylethyl)piperazine (3C-PEP)

Trazodone, nefazodone, etoperidone, mepiprazole, and others produce mCPP as a metabolite.

para-Substituted

4-Chlorophenylpiperazine (pCPP)

4-Fluorophenylpiperazine (pFPP)

4-Methylphenylpiperazine (pMPP)

4-Methoxyphenylpiperazine (pMeOPP, MeOPP)

4-Nitrophenylpiperazine (pNPP; PAL-175) – selective partial serotonin releasing agent

4-Trifluoromethylphenylpiperazine (pTFMPP)

Multiple substitutions

2,3-Dichlorophenylpiperazine (2,3-DCPP)

3,4-Dichlorophenylpiperazine (3,4-DCPP)

2,3-Dimethylphenylpiperazine (DMPP)

3-Trifluoromethyl-4-chlorophenylpiperazine (TFMCPP; PAL-179) – selective partial serotonin releasing agent

Others

1-Phenylpiperazine (PP)

Other arylpiperazines

1-(1-Naphthyl)piperazine (1-NP)

1-(2-Pyrimidinyl)piperazine (1-PP)

6-Chloro-2-(1-piperazinyl)quinoxaline (CPQ)

ORG-12962 (1-(5-trifluoromethyl-6-chloropyridin-2-yl)piperazine)

Quipazine (2-piperazin-1-ylquinoline)

Many azapirones such as buspirone, gepirone, and tandospirone produce 1-PP as a metabolite.

Editorial summary

“Substituted piperazine” enters the record as class of chemical compounds. Crown Archives preserves that source wording while asking what Substituted, piperazine and class can confirm, complicate or overturn.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 183-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Substituted, piperazine and class.
Editorial analysis

Why this record matters

“Substituted piperazine” is worth following because a concise public description often conceals a longer documentary argument. Here, Substituted, piperazine and class provides the most credible route into that argument.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q48836115. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
