Quality Control

Our production of Phosphoric Acid (4-Chlorophenyl)Diethyl Ester adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
