CAS 73-31-4: Melatonin
Description:Melatonin, with the CAS number 73-31-4, is a naturally occurring hormone primarily produced by the pineal gland in the brain. It plays a crucial role in regulating circadian rhythms and sleep-wake cycles. Chemically, melatonin is known as N-acetyl-5-methoxytryptamine, and its molecular formula is C13H16N2O2. It is a small, lipophilic molecule, which allows it to easily cross cell membranes and the blood-brain barrier. Melatonin exhibits antioxidant properties and has been studied for its potential therapeutic effects in sleep disorders, jet lag, and various health conditions related to circadian rhythm disruptions. In terms of physical characteristics, melatonin is typically a white to off-white crystalline powder, soluble in organic solvents like ethanol and dimethyl sulfoxide, but less soluble in water. Its stability can be affected by light and temperature, necessitating careful storage conditions. Overall, melatonin is a significant compound in both biological and pharmacological contexts, with ongoing research into its broader health implications.
