Quality Control

Our Sodium 3-[(5,8-Dichloro-1-Hydroxy-2-Naphthyl)Azo]-2-Hydroxy-5-Nitrobenzenesulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters are provided to guarantee traceability and batch-to-batch consistency, supporting 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 after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
