Quality Control

Our Diammonium 4,4'-[(9,10-Dihydro-9,10-Dioxo-1,4-Anthrylene)Diimino]Bis(Toluene-3-Sulphonate) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) documenting identity, purity, and other critical parameters are provided with every shipment 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 tightly sealed after opening to prevent moisture absorption and potential degradation. Keep away from incompatible materials.
