Quality Control

Our production of 2,3-Dichloropropylphosphonic Acid Bis(2,3-Dichloropropyl) Ester adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications 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 heat sources and incompatible materials. Due to its properties as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere such as nitrogen to maintain product integrity. Keep the container tightly sealed when not in use to minimize moisture uptake and oxidation.
