Quality Control

Our 2,3-Naphthalenedicarbonyl Dichloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases and moisture.
