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”.
