This chemical is primarily used in industrial applications, particularly as a dielectric fluid in electrical equipment like transformers and capacitors due to its stability and insulating properties. It has also been utilized in heat transfer systems and hydraulic fluids. However, its use has significantly declined due to environmental and health concerns, as it is a persistent organic pollutant that can accumulate in ecosystems and pose risks to human health. Research and regulatory efforts now focus on its detection, monitoring, and safe disposal to mitigate its impact on the environment.
