Quality Control

Our Phenyl Dichlorophosphate is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment, ensuring full traceability and compliance with your internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from strong bases and oxidizing agents.
