Quality Control

Our Bis[4-[(5-Sulpho-1-Naphthyl)Azo]Naphthalene-1-Diazonium] Sulphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent purity, reactivity, and performance as a dye intermediate. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and solubility are available upon request to support your quality assurance and production processes.

Storage

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