Flunitrazolam

Flunitrazolam is a benzodiazepine analogue. Flunitrazolam is closely related to clonazolam, and flubromazolam. Flunitrazolam is named for the fluorine, bromine, and triazole substitutions on its core benzodiazepine skeleton (FLUorine-NITro-AZOLe-AM). Flunitrazolam is a member of the benzodiazepine class as it contains a 1,4 diazepine ring fused to a substituted benzene ring. Bromine is bound to this bicyclic structure at R₇. Additionally, a fluorine substituted phenyl ring is bound to this structure at R₅. Flunitrazolam also contains a methylated triazole ring fused to and incorporating R₁ and R₂ of its diazepine ring. Flunitrazolam belongs to a class of benzodiazepines containing this fused triazole ring, called triazolobenzodiazepines, distinguished by the suffix “-zolam”.

IUPAC: 6-(2-fluorophenyl)-1-methyl-8-nitro-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine
