5-MeO-DALT or N,N-diallyl-5-methoxytryptamine is a psychedelic tryptamine first synthesized by Alexander Shulgin.
The full name of the chemical is N-allyl-N-[2-(5-methoxy-1H-indol-3-yl)ethyl]prop-2-en-1-amine.
It is chemically related to the compounds 5-MeO-DPT and DALT.
The first material regarding the synthesis and effects of 5-MeO-DALT was sent from Alexander Shulgin to a researcher
named Murple in May 2004, after which it was circulated online. In June 2004 5-MeO-DALT became available from
internet research chemical vendors. In August 2004 the synthesis and effects of 5-MeO-DALT were published by Erowid.
Doses ranging from 12–20 mg were tested by Alexander Shulgin's research group.
There are numerous anecdotal reports of users consuming dosages far in excess of those tested by Alexander Shulgin,
although there is no published literature on the toxicity of 5-MeO-DALT. By far, the most dangerous effect seems to be
retrograde amnesia from consuming excess amounts of this material.
5-MeO-DALT is unscheduled in the United States. It is also legal in the UK because the allyl group is not an alkyl group,
which the law requires for a tryptamine to be illegal. 5-MeO-DALT became a controlled substance in Japan from April 2007,
by amendment to the Pharmaceutical Affairs Law.
