Δ-3-Tetrahydrocannabinol

Chemical compound

Δ-3-Tetrahydrocannabinol (Delta-3-THC, Δ3-THC, Δ6a(10a)-THC, EA-1477) is a synthetic isomer of tetrahydrocannabinol, developed during the original research in the 1940s to develop synthetic routes to the natural products Δ8-THC and Δ9-THC found in the cannabis plant.[1] While the normal trans configuration of THC is in this case flattened by the double bond, it still has two enantiomers as the 9-methyl group can exist in an (R) or (S) conformation. The (S) enantiomer has similar effects to Δ9-THC though with several times lower potency, while the (R) enantiomer is many times less active or inactive, depending on the assay used.[2][3][4] It has been identified as a component of vaping liquid products.[5]
