Quality Control

Our 6-(1-Naphthylazo)Naphthalene-2-Sulphonic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets precise specifications for industrial and research applications. A Certificate of Analysis (COA) detailing all quality parameters is provided with every shipment.

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 sealed to prevent absorption of atmospheric moisture.
