Quality Control

Our production of 4-[[(3-Aminophenoxy)Acetyl]Amino]-5-Hydroxynaphthalene-1,7-Disulphonic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Every lot is analyzed using advanced techniques like HPLC and NMR to confirm identity and assay. Certificates of Analysis (COA) documenting all critical parameters are provided with each 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 to prevent absorption of atmospheric moisture, which could affect product stability and performance.
