Quality Control

Our Sodium 5-[[4-[(3-Acetamidophenyl)Azo]-2,5-Dimethoxyphenyl]Azo]-6-Amino-4-Hydroxynaphthalene-2-Sulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with every shipment.

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 each use to prevent degradation from atmospheric moisture.
