Used primarily in industrial applications, it serves as a component in dielectric fluids for transformers and capacitors due to its stability and insulating properties. It is also employed in heat transfer systems and hydraulic fluids, where its chemical resistance is advantageous. Additionally, it has been utilized in the past as a flame retardant in various materials, though its use has declined due to environmental and health concerns. Its persistence in the environment has led to strict regulations on its production and disposal.
