HHCP-O-acetate (HHCPO, HHCP-O) is a semi-synthetic derivative of tetrahydrocannabiphorol (THCP) derived in several steps by hydrogenation to hexahydrocannabiphorol (HHCP) followed by acetylation of the OH group. It has been found as a component of grey-market cannabis products such as e-cigarette liquids and edible gumdrops, and is allegedly a potent and long-lasting psychoactive cannabinoid. [1]
Some vendors have mistakenly claimed that HHCPO stands for hexahydrocannabinol propionate (HHC-P) or hexahydrocannabinol cyclopropyl ether, but these are different compounds.

THC-O-acetate is the acetate ester of THC. The term THC-O-acetate and its variations are commonly used for two types of the substance, dependent on which cannabinoid it is synthesized from. The difference between Δ8-THC and Δ9-THC is bond placement on the cyclohexene ring.
9-Nor-9β-hydroxyhexahydrocannabinol is a cannabinoid first discovered from early modifications to the structure of THC, in a search for the simplest compound that could still fulfill the binding requirements to produce cannabis-like activity.
The molecular formula C25H36O3 (molar mass: 384.552 g/mol) may refer to:
AM-2389 is a classical cannabinoid derivative which acts as a potent and reasonably selective agonist for the CB1 receptor, with a Ki of 0.16 nM, and 26× selectivity over the related CB2 receptor. It has high potency in animal tests of cannabinoid activity, and a medium duration of action. Replacing the 1',1'-dimethyl substitution of the dimethylheptyl side chain of classical cannabinoids with cyclopropyl or cyclopentyl results in higher potency than cyclobutyl, but only the cyclobutyl derivatives show selectivity for CB1 over CB2. High selectivity for CB1 over CB2 is difficult to achieve (cf. AM-906, AM-1235), as almost all commonly used CB1 agonists have similar or greater affinity for CB2 than CB1, and the only truly highly selective CB1 agonists known as of 2012 are eicosanoid derivatives such as O-1812.
Cannabis in Denmark is illegal for recreational use, but medical use is allowed through a four-year pilot program initiated in January 2018.
Tetrahydrocannabiphorol (THCP) is a potent phytocannabinoid, a CB1 and CB2 agonist which was known as a synthetic homologue of THC, but for the first time in 2019 was isolated as a natural product in trace amounts from Cannabis sativa. It is structurally similar to Δ9-THC, the main active component of cannabis, but with the pentyl side chain extended to heptyl. Since it has a longer side chain, its cannabinoid effects are "far higher than Δ9-THC itself." Tetrahydrocannabiphorol has a reported binding affinity of 1.2 nM at CB1, approximately 33 times that of Δ9-THC (40 nM at CB1).
Δ-10-Tetrahydrocannabinol is a positional isomer of tetrahydrocannabinol, discovered in the 1980s. Two enantiomers have been reported in the literature, with the 9-methyl group in either the (R) or (S) conformation; of these, the (R) enantiomer appears to be the more active isomer as well as the double bond in the 10th position instead of the 9th maintaining about 30 to 40 percent the potency of delta-9-THC. Δ10-THC has rarely been reported as a trace component of natural cannabis, though it is thought to be a degradation product similar to cannabinol rather than being produced by the plant directly. However, it is found more commonly as an impurity in synthetic delta-8-THC produced from cannabidiol and can also be synthesized directly from delta-9-THC.
Hexahydrocannabinol (HHC) is a hydrogenated derivative of tetrahydrocannabinol (THC). It is a naturally occurring phytocannabinoid that has rarely been identified as a trace component in Cannabis sativa, but can also be produced synthetically by acid cyclization and hydrogenation of cannabidiol. The synthesis and bioactivity of HHC was first reported in 1940 by Roger Adams.
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.
11-Hydroxyhexahydrocannabinol is an active metabolite of tetrahydrocannabinol (THC) and a metabolite of the trace cannabinoid hexahydrocannabinol (HHC).
O-1656 is a cannabinoid agonist which was invented by Billy R Martin and Raj K Razdan at Organix Inc in 2002. It is moderately selective for the CB2 receptor with a CB1 receptor affinity of 18 nM and a CB2 receptor affinity of 2 nM. Since it has a cycloheptyl ring attached to the phenol core, it falls outside the definition of a "cyclohexylphenol derivative", but may still be controlled by generic legislation in some jurisdictions.
JWH-138 (THC-Octyl, Δ8-THC-C8) is a synthetic cannabinoid first synthesised by John W. Huffman, with a Ki of 8.5nM at the CB1 cannabinoid receptor. THC-Octyl and its hydrogenated analog HHC-Octyl was synthesized and studied by Roger Adams as early as 1942.
8-Hydroxyhexahydrocannabinols are active primary metabolites of hexahydrocannabinol (HHC) in animals and trace phytocannabinoids. The 8-OH-HHCs are produced in notable concentrations following HHC administration in several animal species, including humans. They have drawn research interest for their role in HHC toxicology and stereoisomeric probes of the cannabinoid drug/receptor interaction.
HHC-acetate is a semi-synthetic cannabinoid derivative which has been marketed since around 2022. It is believed to be made in a three step process from cannabidiol extracted from hemp. The legal status of hexahydrocannabinol and derivatives such as HHC-O varies between countries leading to widespread sale in some jurisdictions in Europe and the US, but in France HHC and HHC-O were banned in 2023, and HHC is already banned in several other countries. On 1st of March 2024 HHC was banned on Czech Republic.
Hexahydrocannabiphorol is a semi-synthetic cannabinoid derivative which has been marketed since around 2021. It is believed to be made from the hydrogenation of tetrahydrocannabiphorol (THCP). THCP is only reported as a trace component of cannabis in 2019. HHCP was studied by Roger Adams as early as 1942.
Hexahydrocannabihexol (HHCH) is a semi-synthetic cannabinoid derivative. It was first synthesised by Roger Adams in 1942 and found to be more potent than either the pentyl or heptyl homologues, or the unsaturated tetrahydrocannabinol analogue.
THCP-O-acetate (THCP-O) is a semi-synthetic derivative of tetrahydrocannabiphorol (THCP) derived by acetylation of the OH group. It has been found as a component of grey-market cannabis products such as e-cigarette liquids and edible gummy lollies, and is allegedly a potent and long-lasting psychoactive cannabinoid.
Isotetrahydrocannabinol (iso-THC) is a phytocannabinoid similar in structure to cannabicitran which has been identified as a trace component of Cannabis, but is more commonly found as an impurity in synthetic THC which has been made from cannabidiol, along with other isomers with the double bond in a different position and the saturated dihydro derivative. iso-THC can be described as the upper cyclization product of CBD, while THC is the lower cyclization product of CBD. Its pharmacology has not been studied, though it is commonly found as a trace impurity in commercially marketed Δ8-THC products.
Abeo-HHC acetate is a semi-synthetic derivative of tetrahydrocannabinol, first described in the 1980s. It is synthesised from delta-11-tetrahydrocannabinol, which can be made to undergo a ring expansion reaction via a hydrazone intermediate. It is structurally similar to HHC-acetate except it's substituted with a cycloheptyl ring instead of a methylated cyclohexyl ring.
