25B-NBOH
25B-NBOH is a synthetic psychedelic of the substituted phenethylamine class, derived from 2C-B through N-benzylation. First synthesized in 2011 by Martin Hansen at the University of Copenhagen, it is a close structural analog of 25B-NBOMe and is reported to share most of its properties, with moderately reduced potency and a shorter duration. It produces visually dominant and stimulating psychedelic effects, acting as a potent serotonin receptor agonist at 5-HT2A and 5-HT2C receptors.
