This product is an analogue of JWH-018 cannabnoid, with a formal name of 1-naphthalenyl(1-pentyl-1H-indazol-3-yl)-methanone and a molecular formula of C23H22N2O.
To form this analogue, synthesizers substituted an indazole basis for JWH-018's core indole structure.
There hasn't been much information published about THJ-018's biological activities. However; analogues which bear some resemblance to it are known to bind to the brain's CB-1 receptors and also is show to bear some agonist properties.
Because of how structurally similar this product is to those other analogues, it may offer some of the same properties as them.
Researchers may want to consider looking into how THJ-018 relates to JWH-018.
