XLR-12 is an indole-based synthetic cannabinoid drug that was invented by Abbott Laboratories in 2006.^[1] It is an analogue of XLR-11 where the 5-fluoropentyl chain has been replaced with a 4,4,4-trifluorobutyl chain. XLR-12 is relatively highly selective for the CB₂ receptor, with a K_i of 0.09 nM and 167x selectivity over the related CB₁ receptor, however it still retains appreciable affinity for CB₁ with a K_i of 15 nM.^[2]

Legal status

XLR-12 is illegal in Hungary^[3] and Japan.^[4]
