Quality Control

Our Sodium 6-Amino-4-Hydroxy-5-[[4-[[4-[(4-Hydroxyphenyl)Azo]Phenyl]Azo]-6-Methoxy-m-Tolyl]Azo]Naphthalene-2-Sulphonate is produced 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 and consistent performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

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.
