25I-NB34MD (NB34MD-2C-I) is a derivative of the phenethylamine hallucinogen 2C-I, which acts as a potent partial agonist for the human 5-HT<sub>2A</sub> receptor, and presumably has similar properties to 2C-I. It has a binding affinity of 0.67nM at the human 5-HT<sub>2A</sub> receptor, making it several times weaker than its positional isomer 25I-NBMD and a similar potency to 25I-NBF.
