2-Chloromescaline
2-Chloromescaline (2-CM or 2-Cl-M), also known as 2-chloro-3,4,5-trimethoxyphenethylamine, is a serotonin receptor modulator of the scaline family related to mescaline. It has been encountered as an artifact in the isolation of mescaline from the Trichocereus peruvianus (San Pedro/Peruvian torch) cactus with a chlorinated solvent.
