Quality Control

Our Dithiophosphoric Acid O,o-Diethyl S-[2-(Butylthio)Ethyl] Ester is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance as required by our industrial partners. Certificates of Analysis (COA) detailing key specifications such as assay, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from strong bases and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 15-25°C.
