Quality Control

Our 7-Hydroxy-2-Naphthoic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and loss on drying, to ensure it meets exacting specifications for industrial and research applications. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

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. For long-term storage, consider using desiccants or an inert atmosphere to minimize the risk of oxidation.
