Used primarily as a fire extinguishing agent in specialized systems, particularly for protecting valuable assets like electronic equipment, libraries, and museums, where water or other extinguishing agents could cause damage. It is effective in suppressing fires quickly without leaving residue. Additionally, it has been utilized as a refrigerant in certain cooling systems due to its thermal properties. However, its use has declined due to environmental concerns related to ozone depletion and global warming potential. In industrial settings, it has also served as a solvent or intermediate in chemical synthesis processes.
