Quality Control

Our O,o-Dimethyls-Propylphosphorothioate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 acids, bases, and oxidizing agents. Due to its sensitivity, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
