2C-B-BUTTERFLY is a conformationally-restricted derivative of the phenethylamine hallucinogen 2C-B, which was discovered in 1999 by Michael S. Whiteside and Aaron Monte.[1] 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 over 5-HT2A.[2][3]

Legal Status

2C-B-BUTTERFLY is illegal in Latvia.[4]
