Melatonin
1. Basic Product Information
Product Name: Melatonin
CAS Number: 73-31-4
Molecular Formula: C13H16N2O2
Molecular Weight: 232.28
Synonyms: N-Acetyl-5-methoxytryptamine, Melatonine
Product Category: Biochemical raw material, sleep-aid functional food additive, pharmaceutical API, cell culture reagent, anti-oxidant skincare active ingredient
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to pale off-white crystalline powder
- Odor: Odorless
- Solubility: Soluble in ethanol, methanol, DMSO, chloroform; slightly soluble in hot water; insoluble in cold water and aliphatic hydrocarbons
- Melting Point: 116–119 °C
- Density (20 °C): 1.18 g/cm3
- Hygroscopicity: Non-hygroscopic under sealed dry storage
- Aqueous Stability: Unstable in aqueous solution; prone to oxidation and discoloration under UV light, high temperature or alkaline environment
Chemical Characteristics
- Molecular Structure: Indole heterocyclic amide compound, containing methoxy group and acetylaminoethyl side chain
- Core Functional Mechanism: Neuroendocrine hormone secreted by human pineal gland; regulates circadian rhythm, improves sleep quality; possesses anti-oxidation, immune regulation and anti-aging effects
- Photostability: Extremely light-sensitive; light exposure triggers indole ring oxidation to form dark brown impurities and reduce activity
- Thermal Stability: Stable below 60 °C; heating above 90 °C accelerates amide degradation and oxidation
- Chemical Compatibility: Compatible with anhydrous protic solvents and neutral vitamin excipients; incompatible with strong oxidants, concentrated strong alkalis and heavy metal ions
3. Main Application Fields
- Core Application: Functional Food & Health Supplement Raw Material
Sleep-improving additive for sleep-aid tablets, oral liquids and sports nutrition supplements - Pharmaceutical Raw Material
API for sleep regulation, anti-depressant and immune-regulating compound preparations - Cell Culture Biochemical Reagent
Medium additive for mammalian cell culture to reduce oxidative stress damage of cells - High-End Anti-Aging Cosmetic Raw Material
Anti-oxidation, anti-photoaging skincare additive to alleviate skin oxidative damage caused by ultraviolet rays
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Biochemical Reagents
Reason: Indole heterocyclic biochemical raw material widely used in health food, pharmaceutical and biotech industries
2) English Product Group Dropdown Options
