Quality Control

Every batch of our 3,3-Bis(Trifluoromethyl)-4,4,5,5,6,6,6-Heptafluorohex-1-Yne undergoes rigorous analytical testing to ensure high purity and lot-to-lot consistency, critical for sensitive R&D and scale-up processes. Our standard quality protocol includes verification by GC, NMR (19F and 1H), and FTIR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases and fluorides. Due to its highly volatile nature, ensure containers are securely sealed and stored upright. Recommended storage temperature is 2-8°C for long-term stability.
