2,3,5-Trimethoxyphenethylamine (2,3,5-TMPEA), also known as TMPEA-4 or as 2C-TMA-4, is a chemical compound of the phenethylamine family related to mescaline (3,4,5-trimethoxyphenethylamine). [1] [2] [3] [4] [5] It is one of the possible positional isomers of trimethoxyphenethylamine and is a positional isomer of mescaline. [1] [2] [3] [4] According to Alexander Shulgin in his book PiHKAL (Phenethylamines I Have Known and Loved), 2,3,5-TMPEA has never been tested in humans. [1] Unlike mescaline, 2,3,5-TMPEA does not appear to be a substrate for amine oxidase. [3] [1] [2] [5] The chemical synthesis of 2,3,5-TMPEA has been described. [4] The 2,3,5- substitution pattern, as in 2,3,5-TMPEA, is said to be the most difficult tri-substitution pattern in terms of synthesis. [1] 2,3,5-TMPEA was first described in the scientific literature by J. R. Merchant and A. J. Mountwala in 1958. [2] [1] [4] As a positional isomer of mescaline, it is a Schedule I controlled substance in the United States. [2]

"This 2,3,5-orientation of the methoxy groups on the aromatic ring is far and away the most difficult tri-substitution pattern known to chemists. There just isn’t any simple way to put it together. The 2-carbon phenethylamine (2,3,5-trimethoxyphenethylamine) had been synthesized quite a while ago. Its role as a substrate for liver amine oxidase in in vitro studies has been explored, but it has never been tried in man."
