Δ9-Tetrahydrocannabutol (tetrahydrocannabinol-C4, THC-C4, Δ9-THCB, (C4)-Δ9-THC, butyl-THC) is a phytocannabinoid found in cannabis that is a homologue of tetrahydrocannabinol (THC), the main active component of Cannabis.[1] Structurally, they are only different by the pentyl side chain being replaced by a butyl side chain. THCB was studied by Roger Adams as early as 1942 [2]
