Quality Control

Our Di-T-Butyl Phosphoric Acid is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets precise specifications for purity and consistency. Certificates of Analysis (COA) are provided with every shipment, and we support compliance with relevant global regulatory frameworks, including REACH.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. Keep away from incompatible materials such as strong bases and oxidizing agents.
