25I-NBOMe (NBOMe-2C-I, BOM-CI, Cimbi-5, Solaris) is a derivative of the phenethylamine hallucinogen 2C-I, discovered in 2003 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]

25I-NBOMe acts as a highly potent agonist for the human 5-HT2A receptor,[3][4] with a Ki of 0.044 nM, making it some sixteen times the potency of 2C-I itself, and a radiolabelled form of 25I-NBOMe can be used for mapping the distribution of 5-HT2A receptors in the brain.[5][6] In vitro tests showed this compound acted as an agonist but animal studies have not been reported. 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.[7]

Anecdotal reports from human users suggest 25I-NBOMe to be an active hallucinogen at a dose of as little as 500 mcg, making it a similar potency to other phenethylamine derived hallucinogens such as bromo-dragonfly.
