Quality Control

Our 1-Amino-4-[(2,5-Dimethylphenyl)Amino]-9,10-Dihydro-9,10-Dioxo-2-Anthracenesulfonic Acid Sodium Salt is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key specifications such as assay, 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties.
