Quality Control

Our 5-Hydroxy-4-[[(3-Nitrophenoxy)Acetyl]Amino]Naphthalene-1,7-Disulphonic Acid is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (HPLC), related substances, and physical characteristics are available upon request 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 to prevent absorption of atmospheric moisture, which can affect product stability and performance.
