01 /Applications

Melatonin biosynthesis research

N-Acetylserotonin is the immediate precursor of melatonin, formed from serotonin by arylalkylamine N-acetyltransferase and converted to melatonin by acetylserotonin O-methyltransferase. It is widely used as a reference compound in studies of the indoleamine and circadian biosynthetic pathway.

Neurochemistry and cell biology

As a bioactive small molecule of the indole class, it serves as a tool compound in cell biology and neurochemical investigations. It is supplied for laboratory research use only.

Heterocyclic building block

The 5-hydroxyindole scaffold makes this compound a useful building block in chemical synthesis. It can act as a starting material or intermediate in the preparation of related indole and tryptamine derivatives.

Analytical reference standard

With a defined assay and melting point, it can be used as a characterised reference material for chromatographic and spectroscopic method development involving serotonin- and melatonin-related metabolites.
