2,5-Dimethoxy-4-butylamphetamine
group of stereoisomers

2,5-Dimethoxy-4-butylamphetamine (DOBU) is a psychedelic drug of the phenethylamine, amphetamine, and DOx families related to DOM. It is the derivative of DOM in which the methyl group at the 4 position has been replaced with a butyl group. The drug is taken orally.
It acts as a serotonin receptor agonist, including of the serotonin 5-HT2A receptor. The drug produces psychedelic-like effects in animals.
DOBU was first described in the literature by Alexander Shulgin in 1970. Subsequently, it was described in greater detail by Shulgin in his 1991 book PiHKAL (Phenethylamines I Have Known and Loved).
Use and effects
In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin and colleagues stated that doses of 1 to 3 mg orally produced clear threshold effects and that it was active at a dose of slightly more than twice that of DOM. It was stated that 10 mg DOBU was required to produce hallucinogenic effects. The drug's duration was listed as "very long". There was limited investigation of its qualitative effects. However, in PiHKAL, at the assessed doses of 2.2 mg and 2.8 mg, it was described as producing paresthesia and difficulty sleeping with few other effects.
The public source identifies “2,5-Dimethoxy-4-butylamphetamine” as group of stereoisomers. This brief keeps that definition visible, then builds a research path around 5-Dimethoxy-4-butylamphetamine, group and stereoisomers.
Why this record matters
A short description can identify a subject without explaining its stakes. For “2,5-Dimethoxy-4-butylamphetamine”, the useful work is to connect “group of stereoisomers” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q4596790. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1970 and 1991.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
