5-EAPB
chemical compound
5-EAPB, also known as 5-(2-(ethylamino)propyl)benzofuran, is a potentially entactogenic amphetamine and benzofuran which is structurally related to 5-MAPB and 5-APB. It might be predicted to show similar effects to these drugs in humans, but the pharmacology of 5-EAPB remains unstudied as of 2020.
5-EAPB is similar in structure to compounds such as 5-APB which are claimed to be agonists of the 5-HT2C receptor as well as a triple monoamine reuptake inhibitor, however 5-EAPB is not listed as an example in this patent, and it is not yet established to what extent the activity of 5-EAPB resembles that of 5-APB.
Toxicity
Three people in their 30s were hospitalised after each taking approximately 500 mg of 5-EAPB, one of whom later died in hospital, whilst attending Brownstock music festival in Essex, UK on August 31, 2013.
Interactions
Society and culture
Legal status
Singapore
5-EAPB is listed in the Fifth Schedule of the Misuse of Drugs Act (MDA) and therefore illegal in Singapore as of May 2015.
United Kingdom
In the UK, all benzofurans are considered Class B drugs and are therefore illegal.
This brief starts where responsible research should: with the source description of “5-EAPB” as chemical compound. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 22, 2026. The linked authority identifier is Q15405291. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020, 2013 and 2015.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
