Quality Control

Our 2H-Perfluoro-5,8-Dimethyl-3,6,9-Trioxadodecane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use to prevent evaporation and potential concentration changes. Keep away from heat, sparks, and open flame.
