Quality Control

Our (4-Methoxy-Phenoxy)-Acetyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high 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 protocols.

Storage

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