Quality Control

Our Sodium 9,10-Dihydro-1,5-Dihydroxy-4,8-Bis(Methylamino)-9,10-Dioxoanthracene-2-Sulphonate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and color strength 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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
