Perfluoroalkanes are a group of chemical compounds that consist of carbon and fluorine atoms. They are fully fluorinated, meaning all hydrogen atoms in the alkane chain are replaced by fluorine. This unique structure gives them distinct properties, such as high stability and resistance to heat, chemicals, and environmental degradation. These compounds are often used in various industrial applications, including aerospace, electronics, and chemical manufacturing. Due to their persistence in the environment, there are growing concerns about their potential impact on human health and ecosystems, leading to increased regulatory scrutiny and research into safer alternatives.
