Quality Control

Our (2-Chloroethyl)Phosphonic Dichloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, purity, and identity confirmation, to ensure it meets exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its hygroscopic and highly volatile nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature is 2-8°C for long-term stability.
