Flubromazepam is a benzodiazepine derivative which was first synthesized in 1960, but was never marketed and did not receive any further attention or study until late 2012 when it appeared on the grey market as a novel designer drug. It is a structural analog of phenazepam in which the chlorine atom has been replaced by a fluorine atom.
An alternate isomer, 5-(2-bromophenyl)-7-fluoro-1,3-dihydro-2H-1,4-benzodiazepin-2-one or “iso-flubromazepam”, may have been sold under the same name.
This compound was first made in 1960, but was never marketed and did not receive any further attention or study until late 2012. It has potential use for the short-term treatment of anxiety, insomnia, acute seizures, and the sedation of hospitalized patients. However, it is currently exclusively sold by online research chemical vendors for use as a recreational psychoactive substance and has not been formally studied. This means that any comments regarding its pharmacology are purely speculation based upon the subjective effects it induces and its structural similarity to triazolam, pyrazolam and other benzodiazepines.
It’s worth noting that the sudden discontinuation of benzodiazepines can be potentially dangerous or life-threatening for individuals regularly using for extended periods of time, sometimes resulting in seizures or death. It is highly recommended to taper one’s dose by gradually lowering the amount taken each day for a prolonged period instead of stopping abruptly.
Flubromazepam, or 7-Bromo-5-(2-fluorophenyl)-1,3-dihydro-1,4-benzodiazepin-2-one, is a chemical of the benzodiazepine class. Flubromazepam is named for the fluorine and bromine substitutions on its core benzodiazepine skeleton (FLUorine-BROMine-azepam). Flubromazepam 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. Flubromazepam also contains an oxygen group double bonded to R2 of its diazepine ring to form a ketone. This oxygen substitution at R2 is shared with other benzodiazepine drugs with the suffix -azepam.
