Quality Control

Our o-sec-Butyl o-Ethyl Hydrogen Dithiophosphate is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from strong oxidizing agents.
