4F-MDMB-BINACA is classified as an indazole. 4FMDMB-BINACA is based on an indazole core structure, where the 1- and 3-positions of the indazole ring system are substituted. The 1-position of 4F-MDMB-BINACA is substituted with a linear four carbon chain terminated with a fluorine (F) atom. The 3-position is substituted with an amide linker, and the nitrogen (N) atom of this linker is further substituted with a 1-methoxy-3,3-dimethyl-1- oxobutan-2-yl group.
To add, various products containing synthetic cannabinoids in recent years (e.g., JWH-018, UR-144, AKB48, etc.) laced on plant material have been encountered by law enforcement and are smoked for their psychoactive effects. In response to Federal control of these synthetic
cannabinoids, a transition to new synthetic cannabinoids laced on plant material has been observed. 4F-MDMBBINACA is a synthetic cannabinoid recently encountered on the designer drug market and has been found laced on plant material and marketed under the guise of herbal incense products.
