THCP

Δ9-Tetrahydrocannabiphorol

C₂₃H₃₄O₂ 342.52 g/mol Intoxicating

Typical abundancetrace

Receptor targets

CB1 (Kᵢ ≈ 1.2 nM) · CB2 — high-affinity agonist

Mechanism of action

A Δ9-THC homolog whose alkyl side chain is extended from five to seven carbons (heptyl). The longer chain seats more deeply in the CB1 binding pocket, giving an in-vitro CB1 affinity roughly 33× that of Δ9-THC.

Reported effects

EuphoriaAnalgesia (preclinical)Sedation (preclinical)

Common terpenes

Limonene Myrcene Caryophyllene

Research

Isolated in 2019 (Citti et al., Scientific Reports) as a trace natural product. Its high in-vitro receptor affinity does not translate directly to potency per dose; controlled human data are lacking and most commercial material is semi-synthetic.
