Quality Control

Our Bis[4-[(3-Sulphophenyl)Azo]Naphthalene-1-Diazonium] Sulphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements of industrial dye and pigment synthesis. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every shipment to guarantee traceability and compliance with your quality standards.

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 sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and reducing agents.
