Quality Control

Our production of 2-(4-Chloro-2-Methylphenoxy)Propionyl Chloride adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthesis applications. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
