      Product Detail  


    1. Basic Molecular Parameters (Industry Standard)

    Full Name: Melatonin

    IUPAC Name: N-acetyl-5-methoxytryptamine

    Molecular Formula: C₁₃H₁₆N₂O₂

    Molecular Weight: 232.28 g/mol

    CAS Number: 73-31-4

    Appearance: White crystalline powder; mainstream specs: 1g, 5g, 10g per bottle

    Purity: ≥99.0% tested by HPLC; each batch comes with full COA, HPLC report and MSDS

    R&D Background: Melatonin is an endogenous hormone secreted by the mammalian pineal gland. It is a classic compound widely used in circadian rhythm, sleep, antioxidant and immunology laboratory research.

    2. Core Mechanism of Action

    Melatonin targets MT1/MT2 membrane receptors in the suprachiasmatic nucleus of the brain and peripheral tissues to regulate multiple biological pathways:
    • Bind MT1/MT2 receptors to reset the central circadian clock and adjust sleep-wake cycle;
    • Scavenge reactive oxygen species (ROS) directly, reduce lipid peroxidation and alleviate oxidative damage to cells and mitochondria;
    • Modulate the secretion of hypothalamic-pituitary axis hormones to balance neuroendocrine function;
    • Inhibit excessive activation of the HPA axis, lower stress-induced cortisol levels and relieve nervous excitement;
    • Regulate immune cell proliferation and cytokine secretion to exert immunomodulatory effects;
    • Suppress abnormal cell proliferation signaling pathways for anti-aging and oncology-related in vitro studies.

    3. Core Research Efficacy (For Laboratory Research Only)

    Circadian Rhythm & Sleep Research

    Regulate biological clock and prolong slow-wave sleep; core reagent for insomnia, jet lag and sleep disorder cell/animal models.

    Antioxidation & Anti-Aging Assays

    Neutralize free radicals and protect mitochondrial function; widely used in oxidative stress and cellular senescence experiments.

    Neuroendocrine & Anti-Stress Studies

    Balance cortisol and growth hormone secretion; suitable for research on chronic stress, anxiety and neuroendocrine imbalance.

    Immune Regulation Research

    Modulate lymphocyte activity and inflammatory factors; applied to immune dysfunction and low immunity related preclinical trials.

    Tumor Cell In Vitro Experiments

    Interfere with abnormal proliferation of tumor cells; used for basic research on tumor proliferation inhibition.
