Quality Control

Our Disodium 4-[[4-(Acetylmethylamino)-2-Sulphonatophenyl]Amino]-1-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 precise specifications for use in sensitive synthesis processes. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee traceability and compliance with your quality requirements.

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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
