Used primarily as a high-performance heat transfer fluid in advanced cooling systems, especially in data centers and electronic equipment. Its exceptional thermal stability and low environmental impact make it ideal for two-phase immersion cooling, where servers are submerged directly in the liquid to dissipate heat efficiently. It is non-conductive and leaves no residue, allowing safe operation of live electronics. Also employed in some medical applications as a contrast agent or oxygen carrier due to its high gas solubility and biocompatibility. Additionally, it serves as a solvent or carrier in specialty coatings and lubricants where inertness and volatility control are critical.
