Quality Control

Our production of 4,4'-[Methylenebis[(3,5-Dimethyl-4,1-Phenylene)Imino]]Bis[1-Amino-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonic Acid] adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. All materials undergo rigorous 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 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 tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
