Ethylisopropyltryptamine (EiPT), also known as N-ethyl-N-isopropyltryptamine, is a psychedelic drug of the tryptamine family. [1] It is taken orally. [1]
EiPT appears to have been first synthesized and described by Alexander Shulgin. [1]
In his book TiHKAL (Tryptamines I Have Known and Loved), Alexander Shulgin lists the dose of EiPT as 24 to 40 mg and its duration as 4 to 6 hours. [1] According to Shulgin, this compound tends to produce nausea, dysphoria, and other unpleasant side effects. [1] It also seems to largely lack the hallucinatory and visual properties usually associated with psychedelic drugs. [1]
EiPT is short for N-ethyl-N-isopropyltryptamine. [1] The full chemical name of this structure is N-ethyl-N-[2-(1H-indol-3-yl)ethyl]propan-2-amine. The compound is a substituted tryptamine, which all belong to a larger family of compounds known as indolethyl amines. [1]
The chemical synthesis of EiPT has been described. [1]
Analogues of EiPT include 4-HO-EiPT, 5-MeO-EiPT, methylisopropyltryptamine (MiPT), propylisopropyltryptamine (PiPT), ethylpropyltryptamine (EPT), diethyltryptamine (DET), and diisopropyltryptamine (DiPT), among others. [1]
EiPT is unscheduled and uncontrolled in the United States, but possession and sales of EiPT could be prosecuted under the Federal Analog Act because of its structural similarities to DET.[ citation needed ]
