flunitrazolam flunitrazolam flunitrazolam (fntz, flunazolam) is a triazolobenzodiazepine (tbzd), which are benzodiazepine (bzd) derivatives, that has been sold online as a designer drug, and is a potent hypnotic and sedative drug similar to related compounds such as flunitrazepam, clonazolam and flubromazolam. it was first definitively identified and reported to the emcdda early warning system, by an analytical laboratory in germany in october 2016, and had not been described in the scientific or patent literature before this. it is the triazole analogue of flunitrazepam (rohypnol). the addition of the triazole ring to the scaffold increases potency significantly, this is evident as flunitrazolam is reported anecdotally to be active in the microgram level. it is active at 0.1 mg. flunitrazolamlegal statuslegal status ca: schedule iv de: npsg (industrial and scientific use only) uk: under psychoactive substances act identifiers iupac name 1-methyl-8-nitro-6-(2-fluorophenyl)-4h-triazolobenzodiazepine cas number2243815-18-9 ypubchem cid137700379chemspider59718543uniiok0i6htr1ychemical and physical dataformulac17h12fn5o2molar mass337.307 g·mol−13d model (jsmol)interactive image smiles o=(=o)c4ccc2-n1c(c)nnc1cn=c(c2c4)c3ccccc3f inchi inchi=1s/c17h12fn5o2/c1-10-20-21-16-9-19-17(12-4-2-3-5-14(12)18)13-8-11(23(24)25)6-7-15(13)22(10)16/h2-8h,9h2,1h3key:rdlagioillwvtm-uhfffaoysa-n
