Quality Control

Our Disodium 1-Amino-4-[[4-[(2-Bromo-1-Oxoallyl)Amino]-2-Sulphonatophenyl]Amino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent specifications required for dye intermediate applications. Certificates of Analysis (COA) documenting purity, impurity profile, and physical characteristics 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 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 such as strong oxidizing agents.
