tetrahydrocannabihexol tetrahydrocannabihexol tetrahydrocannabihexol (δ9-thch, δ9-parahexyl, n-hexyl-δ9-thc) is a phytocannabinoid, the hexyl homologue of tetrahydrocannabinol (thc) which was first isolated from cannabis plant material in 2020 along with the corresponding hexyl homologue of cannabidiol, though it had been known for several decades prior to this as an isomer of the synthetic cannabinoid parahexyl. another isomer δ8-thch is also known as a synthetic cannabinoid under the code number jwh-124, though it is unclear whether this occurs naturally in cannabis, but likely is due to delta-8-thc itself being a degraded form of delta-9-thc. cannabidihexol (cbdh), 2552798-21-5 jwh-124 (δ8-thch), 20622-30-4 tetrahydrocannabihexolidentifiers iupac name (6ar,10ar)-3-hexyl-6,6,9-trimethyl-6a,7,8,10a-tetrahydrobenzochromen-1-ol cas number36482-24-3pubchem cid161906chemspider142196comptox dashboard (epa)dtxsid90957796 chemical and physical dataformulac22h32o2molar mass328.496 g·mol−13d model (jsmol)interactive image smiles ccccccc1=cc(=c23c=c(cc3c(oc2=c1)(c)c)c)o inchi inchi=1s/c22h32o2/c1-5-6-7-8-9-16-13-19(23)21-17-12-15(2)10-11-18(17)22(3,4)24-20(21)14-16/h12-14,17-18,23h,5-11h2,1-4h3/t17-,18-/m1/s1key:dmjvnnfbmzzlfb-qztjidsgsa-n
