Quality Control

Our Disodium 3-Hydroxy-4-[(2-Hydroxy-4-Methyl-5-Sulphonatophenyl)Methyl]Naphthalene-1-Sulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and spectroscopic methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all relevant specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
