Product Overview

Melatonin, CAS No. 73-31-4, is a high-purity synthetic indoleamine biochemical compound manufactured via professional chemical synthesis technology. The product is refined through multi-gradient reversed-phase high performance liquid chromatography and presents uniform white crystalline powder. All synthesis, purification, filling and sealing procedures are completed in standardized dust-free closed workshops. Every batch undergoes strict HPLC purity testing, residual impurity analysis, microbial limit inspection and comprehensive appearance screening before delivery, ensuring stable batch consistency and reliable experimental repeatability.

This product is exclusively for in-vitro laboratory scientific research use only. It is strictly limited to basic biochemical experiments and cell mechanism studies in academic laboratories and biomedical research institutions. Any scenarios related to human body contact, biological treatment, cosmetic formulation and commercial preparation are not permitted. All production and packaging specifications are customized to meet conventional experimental demands of life science research and biochemical molecular mechanism analysis.

The finished product appears as fine white crystalline powder with uniform texture, no caking, no color deviation and no visible foreign impurities. The HPLC purity is steadily maintained at 99%. Trace residual synthetic fragments, inorganic salts and byproducts are controlled at extremely low levels, effectively avoiding experimental interference in in-vitro circadian rhythm model exploration, cellular neural correlation research and molecular signaling pathway analysis, ensuring accurate and stable experimental data output.

Core Product Advantages

1. Stable Physicochemical Properties The artificially synthesized crystalline structure features high structural stability and strong resistance to molecular degradation. Under standard sealed and low-temperature storage conditions, the valid experimental period can reach 24 months. Professional aluminum cap sealed vial packaging effectively prevents moisture absorption, oxidation and ultraviolet damage during long-distance international transportation, maintaining stable physical and chemical properties for experimental use.

2. Excellent Comprehensive Solubility The crystalline powder dissolves rapidly and completely in conventional laboratory solvents including purified water, PBS buffer and ethanol solution. No insoluble particles, precipitation or suspended residues remain after dissolution. Researchers can prepare multiple concentration gradients flexibly according to different experimental protocols, suitable for cell incubation, chromatographic detection and various biochemical reaction tests.

3. Ultra-Low Interference Impurities Multi-stage gradient HPLC purification thoroughly removes synthetic byproducts, residual raw materials and inorganic impurities. The ultra-low impurity content ensures no negative interference on cell state observation, molecular pathway exploration and biochemical reaction verification, significantly reducing experimental errors and improving data stability.

4. Flexible Custom Packaging Support We provide diversified customized packaging specifications for laboratory trial tests and long-term batch experiments. All vials are sealed with professional butyl rubber stoppers and aluminum flip caps to ensure excellent airtightness and avoid sample deterioration. Customized bulk packaging is available for institutional research projects.

Standard Storage Instructions

1. Short-term Storage (Within 3 Months) Keep the vial tightly sealed, store in a dry and cool environment away from strong light, and preserve at 2°C~8°C refrigerator condition. Reduce frequent opening operations to prevent moisture absorption and molecular structural deterioration.

2. Long-term Storage (Over 3 Months) Complete secondary sealing for the container and store stably at -20°C constant low temperature. Repeated freezing and thawing must be avoided to prevent structural changes and attenuation of experimental activity.

3. Post-dissolution Storage Rules The prepared experimental solution should be used completely within 7 days under 2°C~8°C refrigeration. Waste liquid must be disposed of in accordance with laboratory biochemical waste management standards to avoid solution deterioration and microbial contamination.

Approved Application Scope

This biochemical intermediate is only applicable to basic in-vitro scientific research in life science laboratories, biomedical research institutions and biochemical R&D enterprises, including but not limited to:

1. Molecular structure analysis and structural simulation research of melatonin compounds; 2. In-vitro cell circadian rhythm correlation mechanism research; 3. Cellular neural related biochemical index detection and pathway exploration; 4. Molecular signal transduction mechanism basic experiments; 5. Biochemical reagent formula verification and experimental comparative research.

This product is purely used for laboratory basic research and biochemical analysis, and shall not be used for any commercial development, human-related application or product preparation behavior.
