AB-FUBINACA, or N-[(1S)-1-(Aminocarbonyl)-2-methylpropyl]-1-[(4-fluorophenyl)methyl]-1H-indazole-3-carboxamide, is a synthetic indazolecarboxamide drug as it contains a substituted indazole core. A 4-substituted fluorophenyl group is bound to this indazole core through a methyl group at R1 of the indazole. This indazole is substituted at R3 with a carboxamide group. The terminal amine of this carboxamide is bonded to a substituted propyl chain with an aminocarbonyl group at R1 and a methyl group at R2.
