Used primarily as a highly stable, inert fluid in oxygen-rich environments due to its exceptional resistance to combustion. Commonly found in medical applications such as liquid ventilation, where it helps deliver oxygen directly to the lungs in critically ill patients. Also utilized in electronics testing as a dielectric fluid and in specialized heat transfer systems because of its thermal stability and low reactivity. Its non-polar nature makes it suitable for use in gas chromatography as a reference material or carrier medium. Additionally, employed in research settings for NMR spectroscopy as a temperature calibration standard owing to its sharp, well-defined signals.
