Quality Control

Our Dimethyl(Cyanomethyl)Phosphonate is manufactured under strict 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, purity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for long-term stability.
