Quality Control

Our Sodium 1-Amino-9,10-Dihydro-4-[[(4-Methylphenyl)Sulphonyl]Amino]-9,10-Dioxoanthracene-2-Sulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for demanding industrial and research applications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
