Quality Control

Our Bis(2-Chloroethyl) Vinylphosphonate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Due to its sensitivity, it is recommended to store under an inert atmosphere (e.g., nitrogen) to prevent oxidation and moisture uptake. Recommended storage temperature: 2-8°C for long-term stability.
