2C-B-BUTTERFLY
2C-B-BUTTERFLY is a conformationally-restricted derivative of the hallucinogen 2C-B and a member of the phenethylamine, 2C, and FLY families. It was discovered in 1999 by Michael S. Whiteside and Aaron Monte. It is a ring-expanded homologue of the better known compound 2C-B-FLY, and has similar properties as an agonist for serotonin receptors, but with more selectivity for [5-HT2C receptor|5-HT2C (psychedelics)|2C] over 5-HT2A.
