Quality Control

Our Naphthalene-1,4-Dicarbonyl Dichloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; ensure the container is kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from moisture, heat, and incompatible materials.
