25I-NBOMe (NBOMe-2C-I, BOM-CI or N-(2-methoxybenzyl)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminoethane) is a derivative of the phenethylamine hallucinogen 2C-I, discovered in 2004 by Ralf Heim at the Free University of Berlin,[1] and subsequently investigated in more detail by a team at Purdue University led by David Nichols.[2] It acts as a potent agonist for the 5HT2A receptor with a Ki of 0.044nM at the human 5HT2A receptor, making it some sixteen times the potency of 2C-I itself. In vitro tests showed this compound acted as an agonist but animal studies have not been reported. Interestingly while the N-benzyl derivatives of 2C-I were significantly increased in potency compared to 2C-I, the N-benzyl derivatives of DOI were inactive.[3] Anecdotal reports from human users suggest 25I-NBOMe to be an active hallucinogen at a dose of as little as 500mcg, making it a similar potency to other phenethylamine derived hallucinogens such as bromo-dragonfly.
