Quality Control

Our production of Tetrasodium 9,10-Dihydro-1,5-Dihydroxy-9,10-Dioxo-4,8-Bis[(Sulphonatomethyl)Amino]Anthracene-2,6-Disulphonate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity, spectrophotometry for color strength, and elemental analysis, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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.
