Quality Control

Our Sodium 3-[[4-[(4-Ethoxy-m-Tolyl)Azo]-1-Naphthyl]Azo]Benzenesulphonate is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and batch-to-batch reliability suitable for industrial synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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 after opening to prevent degradation from atmospheric moisture.
