2C (psychedelics)

2C is the main name of the psychedelics of the phenylethylamine family, including methoxy groups at the 2nd and 5th positions of the benzene ring ^[1] . Most of the currently known 2C compounds were first synthesized by Alexander Shulgin in the 1970s and 1980s, and published in his book PiHKAL (“ Phenethylamines I Learned and Loved”). Dr. Shulgin also invented the term 2C, which is an acronym for 2 carbon atoms between the benzene ring and the amino group ^[2] .
