5-HTP (5-Hydroxytryptophan)
WARNING: Chemical reagent intended solely for laboratory, research and analytical purposes. NOT FOR HUMAN OR ANIMAL CONSUMPTION. It is not a medicinal product, dietary supplement or food.
5-Hydroxytryptophan (5-HTP), also known as oxitriptan, is a hydroxylated derivative of the amino acid tryptophan. The compound occurs naturally as a biochemical intermediate and serves as a valuable substrate in studies of biogenic amine metabolic pathways. In the laboratory it is used as a pure analytical standard and reference material in medicinal chemistry and neurochemistry research. The material offered here has a declared purity of ≥99%, making it suitable for applications that demand high reproducibility of results.

Research applications
5-HTP is widely used as a reference standard in liquid chromatography (HPLC) as well as in spectrophotometric and mass spectrometric assays, where it serves for calibration and validation of analytical methods. In biochemical research the compound is employed as a model substrate for studying decarboxylation and hydroxylation reactions of aromatic amino acids, and as a starting material in synthetic work on indole derivatives. Owing to the presence of an indole moiety and a hydroxyl group, 5-HTP is a useful model in investigations of the reactivity of heterocyclic compounds and their behaviour under oxidative conditions. The material is intended solely for use under laboratory conditions, carried out by qualified personnel with appropriate personal protective measures. Storage in a tightly sealed container, in a dry and cool place, away from light and oxidising agents, is recommended to preserve the stability and declared purity of the reagent throughout its analytical shelf life.
