Quality Control

Our 3 5-Dimethylphenylphosphoryl Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are 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, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts with strong acids and organic solvents; keep the container tightly sealed under an inert atmosphere such as nitrogen or argon to prevent degradation. Isolate from incompatible materials.
