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_2A receptor, and presumably has similar properties to 2C-I.^[1] It has a binding affinity of 0.67nM at the human 5-HT_2A receptor, making it several times weaker than its positional isomer 25I-NBMD and a similar potency to 25I-NBF.^[2]^[3]
