Quality Control

Our Potassium Di-tert-Butyl Phosphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration, identification by FT-IR, and impurity profiling, to ensure it meets the high-purity standards required for synthetic applications. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are provided with every shipment and are available upon request.

Storage

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