Chemistry

DOET is in a class of compounds commonly known as substituted amphetamines; its full chemical name is 4-ethyl-2,5-dimethoxy-alpha-methylbenzeneethanamine, or 1-(2,5-dimethoxy-4-ethylphenyl)propan-2-amine. It has an active stereocenter and (R)-DOET is the more active enantiomer. DOET is an extremely rare compound and reports of its effects and toxicology in humans are sparse. However, like the more common 2,5-dimethoxy-amphetamine analogues DOB, DOI and DOM, it is a potent and long-acting psychedelic. Removal of the alpha-methyl moiety yields the 2-carbon analogue, commonly known as 2C-E, another psychedelic compound first synthesized by Dr. Alexander Shulgin.

Pharmacology

Similarly to related drugs like DOM, DOET likely acts as a 5-HT_2A, 5-HT_2B, and 5-HT_2C receptor partial agonist. It is an agonist of human TAAR1.^[2]^[3]

Effects

DOET produces psychedelic effects that last up 14-20 hours. In PiHKAL, Shulgin lists the dosage of DOET as being 2-7 mg orally, with 6-7 mg being the dosage for full, desired effects.^[1]

Legality

DOET is classified as a Schedule 1 substance in the United States, and is similarly controlled in other parts of the world. Internationally, DOET is a Schedule I drug under the Convention on Psychotropic Substances [2].
