It is used as a specialty solvent in electronics cleaning as a working fluid in vapor phase soldering and in chemical research due to its chemical inertness and low surface tension.

Its primary purpose is heat transfer and precision cleaning leveraging high thermal stability non-flammability and selective solvency for fluoropolymers while being a PFAS with long atmospheric lifetime (31 years)
