Metabolite Identification
Common Name5-Methoxytryptamine
Description5-Methoxytryptamine, also known as mexamine or 5-meot, belongs to the class of organic compounds known as tryptamines and derivatives. Tryptamines and derivatives are compounds containing the tryptamine backbone, which is structurally characterized by an indole ring substituted at the 3-position by an ethanamine. 5-Methoxytryptamine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. 5-Methoxytryptamine exists in all living organisms, ranging from bacteria to humans.
