Melatonin
Chemical reagent intended exclusively for laboratory, research and analytical purposes. NOT FOR CONSUMPTION by humans or animals. It is not a medicinal product, dietary supplement or food.
Melatonin (N-acetyl-5-methoxytryptamine) is a naturally occurring indoleamide organic compound and a metabolite of serotonin within the tryptophan pathway. As a laboratory reagent, melatonin is a high-purity analytical standard widely used in chronobiological and neurochemical research as well as in analytical chemistry. The molecule combines an indole moiety, a methyl ether and an amide group, making it an interesting subject for studies of the reactivity and stability of heterocyclic compounds. The material offered here has a declared purity of ≥99%, ensuring reproducibility and reliability of results in quantitative applications.

Research applications
Melatonin is widely used as a reference standard in liquid chromatography coupled with mass spectrometry (LC-MS/MS) and in HPLC methods with fluorescence detection, where its characteristic spectral properties allow precise quantitative determinations. In neurochemical and chronobiological research the compound serves as a model material in studies of indoleamine metabolic pathways and antioxidant mechanisms at the molecular level. Melatonin is also a valuable substrate in work on free-radical scavenging reactions and in photostability studies of indole compounds, since the methoxy and amide groups influence its susceptibility to oxidation and degradation. In analytical chemistry it is used as a standard for validating methods for determining trace amounts of biogenic amines in biological and environmental samples. The material is intended solely for laboratory applications carried out by qualified personnel. Because of its light sensitivity, storage in UV-protective packaging, in a cool and dry place, is recommended to maintain the stability and declared purity of the reagent.
