Quality Control

Our Disodium 1-Amino-4-[[4-[[[(2,3-Dichloro-6-Quinoxalinyl)Carbonyl]Methylamino]Methyl]-2-Sulphonatophenyl]Amino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonate 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 dye intermediate applications. Certificates of Analysis (COA) documenting purity, impurity profile, and physical characteristics are available upon request.

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. Keep away from incompatible materials.
