Description

Product Detail

1. Chemical Identity

• IUPAC Name: N-[2-(5-Methoxy-1H-indol-3-yl)ethyl]acetamide

• CAS Registry Number: 73-31-4

• Molecular Formula: C₁₃H₁₆N₂O₂

• Molecular Weight: 232.28 g/mol

• Common Names: Melatonin; N-Acetyl-5-methoxytryptamine.

2. Primary Function: Hormone and Antioxidant

Melatonin is a naturally occurring neurohormone primarily secreted by the pineal gland in humans and animals. It regulates circadian rhythms (sleep-wake cycles) and exhibits potent antioxidant activity by scavenging free radicals and stimulating antioxidant enzymes.

3. Key Properties

• Solubility: Sparingly soluble in water; soluble in organic solvents (e.g., ethanol, DMSO).

• Biological Half-Life: Short (~20–50 minutes), necessitating controlled-release formulations for prolonged effects.

• Reactivity:

◦ Sensitive to light and oxidative degradation.

◦ The indole ring and methoxy group contribute to its radical-scavenging ability.

• Spectroscopy: Exhibits fluorescence due to the indole chromophore.

4. Applications

Pharmaceuticals:

Sleep Disorders: Used to treat insomnia, jet lag, and shift work sleep disorder.

Antioxidant Therapy: Investigated for neuroprotection, anti-aging, and mitigating oxidative stress.

Oncology: Studied for potential anti-cancer effects and reducing chemotherapy side effects.

Dietary Supplements: Marketed as over-the-counter sleep aids and circadian rhythm regulators.

Animal Husbandry: Used to adjust reproductive cycles in livestock.

Cosmetics: Incorporated into skincare products for its antioxidant and anti-aging properties.
