Quality Control

Our 3,3,4,4,4-Pentafluorobutyl Bromide is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 acids, bases, and oxidizing agents. Due to its sensitivity to light, the container should be amber-colored or stored in a dark place.
