Quality Control

Our Hexafluoro-4-(Trifluoromethyl)Pent-2-Enoyl Chloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for sensitive synthetic applications. Each lot is analyzed via GC, NMR, and FTIR to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures between 2°C and 8°C. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening and protected from moisture ingress. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
