9-Hydroxyhexahydrocannabinol

9-Hydroxyhexahydrocannabinol (9-OH-HHC) is a semi-synthetic derivative of tetrahydrocannabinol. It is formed as an impurity in the synthesis of Delta-8-THC, and retains activity in animal studies though with only around 1/10 the potency of Δ9-THC, with the 9α- and 9β- enantiomers having around the same potency.
