tetrahydrocannabiorcol tetrahydrocannabiorcol δ9-tetrahydrocannabiorcol (δ9-thcc, (c1)-δ9-thc) is a phytocannabinoid found in cannabis pollen. it is a homologue of thc and thcv with the alkyl side chain replaced by a smaller methyl group. unlike thc and thcv, thcc has negligible affinity for the cb1 and cb2 cannabinoid receptors because of the smaller methyl group and does not have psychoactive effects as a result, but conversely it is significantly more potent than thc or thcv as an activator of the trpa1 calcium channel which plays an important role in pain perception, and it has been shown to produce analgesic effects via activation of spinal trpa1 channels. tetrahydrocannabiorcolidentifiers iupac name (6ar,10ar)-3,6,6,9-tetramethyl-6a,7,8,10a-tetrahydrobenzochromen-1-ol cas number22972-65-2pubchem cid22805649chemspider18522304unii5d633laj19chemical and physical dataformulac17h22o2molar mass258.361 g·mol−13d model (jsmol)interactive image smiles cc1=c2(cc1)c(oc3=cc(=cc(=c23)o)c)(c)c inchi inchi=1s/c17h22o2/c1-10-5-6-13-12(7-10)16-14(18)8-11(2)9-15(16)19-17(13,3)4/h7-9,12-13,18h,5-6h2,1-4h3/t12-,13-/m1/s1key:widiparnvyrvnw-chwsqxevsa-n
