Quality Control

Our 4-Methoxy-1-Naphthoyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place 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) to prevent degradation. Keep away from heat, open flames, and incompatible materials.
