Application

Perfluoromethyldecalin is widely utilized as a heat transfer fluid and dielectric coolant in high-temperature and corrosive environments due to its exceptional thermal and chemical stability. Its hydrophobic and lipophobic properties make it valuable in the formulation of specialty coatings and surfactants for water- and oil-repellent applications. Researchers also employ it as a solvent or reaction medium in fluorination chemistry and as a reference standard in analytical techniques such as GC-MS and NMR.
