2C (psychedelics)

From Wikipedia, the free encyclopedia

2C (2C-x) is a general name for the family of psychedelic phenethylamines containing methoxy groups on the 2 and 5 positions of a benzene ring.[1] Most of these compounds also carry lipophilic substituents at the 4 position, usually resulting in more potent and more metabolically stable and longer acting compounds.[2] 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 Have Known And Loved). Shulgin also coined the term 2C, being an acronym for the 2 carbon atoms between the benzene ring and the amino group.[3]
