This chemical is primarily used in industrial applications, particularly as a dielectric fluid in electrical equipment such as transformers and capacitors. Its stability and insulating properties make it effective for managing high voltage and heat in these devices. Additionally, it has been utilized in the production of heat transfer fluids and hydraulic systems due to its thermal stability. However, its use has significantly declined due to environmental and health concerns, as it is classified as a persistent organic pollutant. Efforts are now focused on its safe disposal and remediation of contaminated sites.
