Quality Control

Our 1,6-Dihydroxynaphthalene-2,5-dicarboxylic acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing results from HPLC, IR spectroscopy, and other relevant tests to guarantee consistency and compliance with your project requirements.

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 absorption of atmospheric moisture, which can affect product quality and stability.
