Tetrafluoromethane, also known as carbon tetrafluoride or CF4, is a colorless, odorless gas that is used primarily in the production of fluoropolymers and as a refrigerant. It is a stable compound that does not easily react with other substances, making it useful in various industrial applications. In the atmosphere, tetrafluoromethane is considered a potent greenhouse gas, with a global warming potential significantly higher than that of carbon dioxide. Its long atmospheric lifetime raises concerns about its impact on climate change, prompting efforts to monitor and reduce its emissions.
