Quality Control

Our Hexafluoro-2-Butyne is produced and handled under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity (typically by GC), identity confirmation, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area, preferably at controlled room temperature (15-25°C). Keep away from strong alkalis and other incompatible materials. Containers must be kept tightly sealed and upright to prevent leakage and pressure build-up.
