Quality Control

Our Phosphorus Oxychloride is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including assay and impurity profile analysis, to meet exacting customer and industry specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

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 bases, alcohols, and water. Due to its nature as a strong acid/organic solvent, ensure containers are kept tightly sealed to prevent moisture absorption and fume release. Recommended storage temperature is 15-25°C.
