Tetrahydrocannabihexol (Δ9-THCH, Δ9-Parahexyl, n-Hexyl-Δ9-THC) is a phytocannabinoid, the hexyl homologue of tetrahydrocannabinol (THC) which was first isolated from Cannabis plant material in 2020 along with the corresponding hexyl homologue of cannabidiol,[1][2] though it had been known for several decades prior to this as an isomer of the synthetic cannabinoidparahexyl.[3] Another isomer Δ8-THCH is also known as a synthetic cannabinoid under the code number JWH-124,[4][5] though it is unclear whether this occurs naturally in Cannabis, but likely is due to Δ8-THC itself being a degraded form of Δ9-THC.
THC-Hexyl can be synthesized from 4-hexylresorcinol and was studied by Roger Adams as early as 1942.[6]
