Quality Control

Our 1,4-Dihydroxy-2-Naphthoic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize exposure to air and moisture.
