Quality Control

Our (2-Chloro-5-Methylphenoxy)Acetyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (IR, NMR), to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request 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). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
