Hexahydrocannabinol (HHC) has attracted increasing attention in recent years as a novel cannabinoid. This comprehensive article highlights the current state of research on HHC , analyzes existing studies, and identifies research gaps.
The aim is to provide a deep understanding of the scientific findings on HHC while also highlighting the need for further research.
Chemical properties and synthesis of HHC
HHC was first synthesized in 1940 by the American chemist Roger Adams. The compound is produced by the hydrogenation of THC , whereby hydrogen molecules are inserted into the THC structure.
This leads to saturation of the double bonds in the cyclohexenyl ring. Modern manufacturing methods often use CBD as a starting material, which is first converted to Δ8- or Δ9-THC and then hydrogenated.
Isomers and their significance
Studies on HHC have shown that the compound exists as a mixture of two diastereomers: 9α-HHC and 9β-HHC. Interestingly, these isomers exhibit different psychoactive properties, with 9β-HHC showing a stronger effect and a higher affinity for cannabinoid receptors.
This finding underlines the complexity of HHC research and the need to closely examine the specific properties of each isomer.
