Quality Control

Our Tetrasodium 2-[[8-[[3-[(5-Chloro-2,6-Difluoro-4-Pyrimidinyl)Amino]Benzoyl]Amino]-1-Hydroxy-3,6-Disulphonato-2-Naphthyl]Azo]Naphthalene-1,5-Disulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting key 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to minimize exposure to atmospheric humidity. Keep away from incompatible materials.
