Flubromazepam is the name used for a benzodiazepine derivative which was first made in 1960,[1] but was never marketed and did not receive any further attention or study until it started to be sold as a research chemical in late 2012. Its closest relative is phenazepam. Replacing the 2'-Cl with a 2'-F is the single alteration. Flubromazepam is currently being studied.[2] It presumably has sedative, hypnotic, muscle relaxant, and antiepileptic effects common to all benzodiazepine derivatives. A closely related compound, 5-(2-bromophenyl)-7-fluoro-1,3-dihydro-2H-1,4-benzodiazepin-2-one,[3] also appears to have been sold under the same name. Its onset is around 4 hours and reaches its peak at 8 hours.[citation needed]
