Quality Control

Our production of Dipotassium 4,4'-[(9,10-Dihydro-9,10-Dioxo-1,4-Anthrylene)Diimino]Bis(Toluene-3-Sulphonate) adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance as a dye intermediate. Certificates of Analysis (COA) detailing key specifications such as assay, impurity profile, and solubility are provided and available upon request to support your quality assurance processes.

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 quality and handling properties.
