Quality Control

Our 3-[[5-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-2-Sulphophenyl]Azo]-1,2-Dihydro-6-Hydroxy-2-Oxoisonicotinic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive synthesis processes. Certificates of Analysis (COA) detailing all quality parameters are available upon request to support your quality assurance and regulatory needs.

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 tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
