Melatonin is a methoxyindole compound secreted by the pineal gland in the mammalian brain. It regulates the sleep-wake cycles (circadian rhythm) and also has anti-inflammatory and antioxidant properties.

Melatonin pharmaceutical reference standard may also be used as follows:

• Development and validation of a high-performance liquid chromatography (HPLC) method combined with UV detection to determine melatonin in capsule dosage forms
• Determination of melatonin in dog plasma samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS) method
• Simultaneous electrochemical analysis of melatonin and 5-hydroxytryptophan by poly-(melamine)/poly-(o-aminophenol) modified screen printed electrodes (SPCs) in human urine samples
• Determination of melatonin in pharmaceutical formulations by voltammetric and amperometric methods using carbon black modified glassy carbon electrode
• Electroanalytical determination of melatonin in tablet and human urine samples using a boron-doped diamond electrode and square-wave voltammetry (SWV)
• Development of nanopalladium polymeric nanocomposite modified glassy carbon electrode (GCE) for qualitative and quantitative analyses of melatonin in tablets and human urine samples by square-wave voltammetry
• Liquid chromatography-diode array detection (LC-DAD) of melatonin dose in supplements and also detection of impurities present in supplements by ultra-high-performance liquid chromatography-orbitrap mass spectrometry (UHPLC-orbitrap-MS)

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards
