Quality Control

Our O,o-Bis(2-Ethylhexyl) Hydrogen Thiophosphate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and purity verification by GC or HPLC, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

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 and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment and ensure containers are kept tightly sealed to prevent moisture ingress and degradation.
