# 25I-NB34MD

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. 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.
