Quality Control

Our production of Dithiophosphoric Acid S-[2-(Acetyloxy)Ethyl] O,O-Diethyl Ester adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from strong bases and sources of ignition. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at 15-25°C is acceptable.
