Quality Control

Every batch of 4,5,5,5-Tetrafluoro-4-(Heptafluoropropoxy)Pentanoic Acid is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the precise requirements for advanced synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied 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). Due to its nature as a strong acid/organic solvent and high volatility, ensure containers are kept tightly sealed and away from heat, sparks, and open flame. Keep separated from incompatible materials such as strong bases and oxidizing agents.
