H2CBD (diHydroCBD, partially hydrogenated CBD) are cannabinoids that were first synthesized by Alexander R. Todd in 1940 by catalytic hydrogenation of cannabidiol.^[1]

The term "H2CBD" can refer to two different chemical compounds that differ by the site of hydrogenation, either saturated on the cyclohexenyl ring (i.e. 1,2-dihydrocannabidiol using the older terpenoid numbering scheme) or saturated on the isopropenyl side group, which is known as 8,9-dihydrocannabidiol.

H2CBD, H4-CBD, and 8,9-dihydrocannabidiol have all been referred to as "hydrogenated CBD" which may cause confusion.

Pharmacology

In 2006, it was discovered that 8,9-dihydrocannabidiol binds very weakly to the CB1 receptor with a binding affinity higher than 1 μM, but has potential anti-inflammatory effects independent of its cannabinoid receptor action.^[2]
