25B-NBOMe (NBOMe-2C-B, BOM 2-CB, Cimbi-36, New Nexus) is a derivative of the phenethylamine hallucinogen 2C-B, discovered in 2004 by Ralf Heim at the Free University of Berlin. It acts as a potent partial agonist for the 5HT2A receptor.[1][2][3] Anecdotal reports from human users[citation needed] suggest 25B-NBOMe to be an active hallucinogen at a dose of as little as 400-650mcg insufflated,[citation needed] making it a similar potency to other phenethylamine derived hallucinogens such as bromo-dragonfly. Duration of effects lasts about 10h.[citation needed]

The carbon-11 labelled version of this compound ([11C]Cimbi-36) was synthesized and validated as a radiotracer for positron emission tomography (PET) in Copenhagen.[4][5][6] As a 5-HT2A receptor agonist PET radioligand, [11C]Cimbi-36 was hypothesized to provide a more functional marker of these receptors. Also, [11C]Cimbi-36 is investigated as a potential marker of serotonin release and thus could serve as an indicator of serotonin levels in vivo. Distubances in both 5-HT2A receptor signalling and serotonin levels are involved in the pathophysiology of human diseases such as depression and schizophrenia.
