Quality Control

Our 2-Hydroxy-3-Naphthoic Acid Ethanolamide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR spectroscopy, to ensure it meets precise specifications for use in sensitive applications like pigment synthesis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

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 after opening to prevent moisture absorption, which can affect product quality and handling properties.
