The title compound, serotonin or 5-hydroxytryptamine (5-HT) [systematic name: 3-(2-aminoethyl)-1H-indol-5-ol], C10H12N2O, has one molecule in the asymmetric unit. The conformation of the ethylamino side chain is gauche-gauche [Ca-Ca-Cm-Cm and Ca-Cm-Cm-N (a = aromatic, m = methylene) torsion angles =-64.2(3) and-61.9(2)°, respectively]. In the crystal, the molecules are linked into a three-dimensional network by N-H..O and O-H..N hydrogen bonds.
