2,3,4,6-Tetramethoxyphenethylamine

2,3,4,6-Tetramethoxyphenethylamine, also known as TeMPEA-2, is a drug of the phenethylamine family related to the psychedelic drug mescaline. It is one of the possible positional isomers of tetramethoxyphenethylamine. The in-vitro metabolism and effects of TeMPEA-2 on behavior in animals have been studied. The drug showed little or no activity as a norepinephrine releasing agent in vitro. It does not seem to have been tested in humans. TeMPEA-2 was first described in the scientific literature by 1955. It is a controlled substance in Canada under phenethylamine blanket-ban language.
