Quality Control

Our production of Disodium 3,3'-[(9,10-Dihydro-5,8-Dihydroxy-9,10-Dioxo-1,4-Anthrylene)Diimino]Bis[6-Butylbenzenesulphonate] adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure high purity, consistent chromophore strength, and batch-to-batch reproducibility. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided to guarantee the material meets your specific application requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance and stability.
