Quality Control

Our production of 1-Amino-4-[(4-Butylphenyl)Amino]-9,10-Dihydro-9,10-Dioxoanthracene-2-Sulphonic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced techniques like HPLC and NMR to verify identity and assay. Certificates of Analysis (COA) documenting purity, impurity profile, and physical characteristics 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 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 stability and performance.
