Δ-7-Tetrahydrocannabinol

Δ-7-Tetrahydrocannabinol (Delta-5-THC, Δ5-THC; alternatively numbered as Δ-5-Tetrahydrocannabinol, Δ7-THC) is a synthetic isomer of tetrahydrocannabinol. The (6aR,9S,10aR)-Δ7-THC epimer is only slightly less potent than Δ9-THC itself, while the (9R) enantiomer is much less potent.[1][2]
