1H-Undecafluoropentane is primarily used as a heat transfer fluid in various cooling systems, including electronics and data centers, due to its excellent thermal stability, non-flammability, and low global warming potential. It is also employed as a dielectric fluid in electronic applications, providing insulation and cooling for high-voltage equipment. Additionally, it is utilized in the semiconductor and precision manufacturing industries for cleaning and drying processes, where its low surface tension, high density, and chemical inertness make it effective for removing contaminants without damaging sensitive components. It serves as an environmentally friendly alternative to ozone-depleting solvents in industrial applications.
