PB-22 , first reported in 2013, introduced 8-hydroxyquinoline as a substitution for the naphthalene group on traditional JWH-type synthetic cannabinoids. [1][2] The analog NPB-22 differs from PB-22 by the replacement of indazole for indole. FUB-NPB-22 is an analog of NPB-22 in which the pentyl side chain is replaced by a 4-fluorobenzyl group. The physiological and toxicological properties of this compound are not known. This product is intended for forensic and research applications.
