Quality Control

Our (2-Chlorophenoxy)Acetyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to confirm identity and assay. A Certificate of Analysis (COA) detailing purity, impurity profile, and other critical parameters is provided with each shipment to support your quality assurance processes.

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). This compound is hygroscopic (moisture-sensitive) and reacts with water and alcohols; 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.
