Quality Control

Our Sodium 6-Amino-5-[(3,4-Dichlorophenyl)Azo]-4-Hydroxynaphthalene-2-Sulphonate is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting industry standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and consistency for our global B2B clients.

Storage

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