ISBN978-1-4757-0512-6. 3.3.3. 2-Ethoxy-4,5-dimethoxyphenylisopropylamine The ortho-ethoxy homolog of TMA-2 (34) is 2-ethoxy-4,5-dimethoxyphenylisopropylamine (61, EMM, 2-ethoxy-4,5-dimethoxyamphetamine). Acute trials have been conducted to levels (30 mg of the hydrochloride salt, orally) more than twice those which precipitate threshold effects with either MEM (60) or TMA-2 (34) (Shulgin, 1968). No effects either central or peripheral were noted, indicating that EMM would be less than half as potent as these latter drugs as a psychotomimetic, if indeed it had that action at all.
