Melatonin
Melatonin (CAS 73-31-4) is N-acetyl-5-methoxytryptamine, an indoleamine with formula C13H16N2O2 and molecular mass 232.28 g/mol. It is produced mainly by the pineal gland and functions as a hormone involved in circadian timing and sleep–wake signaling. Its actions include signaling through MT1 and MT2 receptors. Commercial reference materials are commonly described as white to off-white crystalline solids; confirm appearance, identity, assay, and any other specification against the lot-specific certificate of analysis rather than assuming all grades are interchangeable.
The compound is used in laboratory studies of circadian biology and melatonin-receptor signaling, and as an analytical reference where suitable. Melatonin is also marketed as an ingredient in some regulated products, but availability, permitted uses, classification, and claims vary by jurisdiction.
– Research reagent for studies of circadian biology, sleep–wake signaling, and melatonin-receptor pathways. Confirm that the grade and documentation are appropriate for the specific experimental system; research observations should not be presented as demonstrated clinical effects or approved therapeutic uses.
– Analytical reference material for identity, assay, or method-development work when its assigned specification and traceability meet the method’s requirements. Check the certificate of analysis, purity, and storage history, and establish suitability in the intended analytical procedure.
– Potential ingredient in a pharmaceutical, supplement, food, feed, or other regulated product only where the substance, grade, product category, and proposed use are permitted by the applicable jurisdiction. Confirm regulatory status, impurity limits, labeling, and claim requirements before product development or sale; do not infer authorization from research use or supplier availability.
