N-Benzyl-2C-B (25B-NB, NB-2C-B) is a recreational designer drug from the 25-NB subgroup of the substituted phenethylamine family, with psychedelic effects. It has a binding affinity (K_i) of 16 nM at the serotonin receptor 5-HT_2A and 90 nM at 5-HT_2C and reportedly has a potency in between that of 2C-B and NBOMe-2C-B.^[1]^[2]
