4-HO-MET, or 4-hydroxy-N-ethyl-N-methyltryptamine, is a synthetic indole alkaloid molecule of the tryptamine\u00a0chemical class. Tryptamines share a core structure comprised of a bicyclic indole heterocycle attached at R3<\/sub>\u00a0to an amino group via an ethyl side chain. 4-HO-MET is substituted at R4<\/sub>\u00a0of its indole heterocycle with a hydroxyl functional group OH\u2212. It also contains a methyl group and an ethyl chain bound to the terminal amine RN<\/sub>\u00a0of its tryptamine backbone (MET).<\/p>\n
