EEE (drug)

EEE, also known as 2,4,5-triethoxyamphetamine or as TMA2-2,4,5-TriEtO, is a chemical compound of the phenethylamine, amphetamine, and DOx families. It is the analogue of TMA-2 in which the three methoxy groups on the phenyl ring have been replaced with ethoxy groups. In his book PiHKAL, Alexander Shulgin lists EEE's dose and duration as unknown. Shulgin stated that EEE has never been tested in humans. The chemical synthesis of EEE has been described. EEE was first described in the scientific literature by Shulgin in 1968. Subsequently, it was described in greater detail by Shulgin in PiHKAL in 1991.
