Melatonin – High Purity Premium API

Product Overview Melatonin, also known as N-Acetyl-5-methoxytryptamine, is an endogenous indoleamine hormone secreted by the mammalian pineal gland. It regulates circadian rhythm and sleep-wake cycle, eliminates intracellular reactive oxygen species to exert powerful antioxidant effects, modulates systemic immune function, and slows down cellular senescence progression. Different from synthetic peptides, it has excellent oral and solution stability without structural degradation. It is applied in laboratory research including circadian rhythm regulation, oxidative stress relief, immune homeostasis modulation, neuroprotection and anti-aging pharmacological mechanism tests. It is extensively adopted in nervous system signaling pathway exploration, antioxidant pharmacodynamic verification and neuroendocrine pharmacological evaluation. Adopting optimized chemical asymmetric synthesis and recrystallization purification technology, the product boasts outstanding water solubility and ultra-long stable biological activity under conventional low-temperature storage. CAS Number: 73-31-4

Technical Specifications & Quality Standards
