Melatonin, also known as 5-methoxy-N-acetyltryptamine, is a substituted tryptamine and hormone secreted endogenously by the pineal gland. It is closely related in chemical structure to serotonin, N-acetylserotonin, 5-methoxytryptamine and 5-MeO-DMT. It can be used as a regulator of circadian rhythm. It acts as an agonist at the melatonergic receptors in the human brain. This compound is not available as a salt or freebase form simply because it does not form salts (melatonin on its own has a neutral charge). This is because the amide bond acts as an electron withdrawing group.
This compound is NOT for human consumption and is available for research purposes only.
