C2F6, or perfluoroethane, is a colorless, odorless gas that belongs to the family of fluorinated gases. It is composed of two carbon atoms and six fluorine atoms, making it a fully fluorinated compound. C2F6 is primarily used in the semiconductor industry for etching and cleaning processes due to its chemical stability and effectiveness. This compound has a high global warming potential, which means it can contribute significantly to climate change if released into the atmosphere. As a result, its use is regulated in many countries, and efforts are being made to find alternatives that are less harmful to the environment.
