Quality Control

Our production of 2-[[4-[[4-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]-5-Sulpho-1-Naphthyl]Azo]-2,5-Dimethylphenyl]Azo]Benzene-1,4-Disulphonic Acid adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing including HPLC for purity and identity confirmation to ensure compliance with industry specifications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance processes.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
