11-Hydroxyhexahydrocannabinol (11-OH-9β-HHC, alternatively numbered as 7-OH-HHC) is a minor active metabolite of tetrahydrocannabinol, and also a metabolite of the trace cannabinoid hexahydrocannabinol.[1]

11-OH-9β-HHC is the structurally related methylene homologue of 11-Nor-9β-hydroxyhexahydrocannabinol also known as 9-Nor-9β-hydroxyhexahydrocannabinol.[2][3]

The structurally related synthetic dimethylheptyl analog of 11-OH-9β-HHC is known as HU-243. The only difference between HU-243 and 11-OH-9β-HHC is that HU-243 features a di (2) methyl groups on its tail chain that has been extended from pentyl (5 carbon atoms)) to heptyl (7 carbon atoms) which significantly increases its binding affinity to the CB1 and CB2 receptors.[4]
