Quality Control

Our Phenoxyacetyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling by GC/HPLC, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with every shipment to guarantee compliance with your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and moisture-sensitive nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases, oxidizers, and moisture.
