Quality Control

Our Sodium 2'-[4-[[2,4-Dihydroxy-3-(Phenylazo)Phenyl]Azo]Phenyl]-6-Methyl[2,6'-Bibenzothiazole]-7-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 specifications for dye synthesis. Certificates of Analysis (COA) documenting purity, heavy metal content, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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, which can affect product performance.
