Quality Control

Our Disodium 5-[[4-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Methylamino]Phenyl]Azo]-2-[2-(4-Nitro-2-Sulphonatophenyl)Vinyl]Benzenesulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive dye synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance 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 to prevent absorption of atmospheric moisture, which can affect product stability and performance.
