Quality Control

Our Tetrafluoroterephthalic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, Karl Fischer titration for moisture, and ICP-MS for heavy metal screening, to ensure it meets the high standards required for advanced synthetic applications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
