Quality Control

Our Sodium 1-Amino-9,10-Dihydro-4-[(4-Methyl-2-Nitrophenyl)Amino]-9,10-Dioxoanthracene-2-Sulphonate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (HPLC), related substances, and physical properties are available upon request. We can support compliance with cGMP, ISO, and other relevant quality standards for industrial and research applications.

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.
