Primarily used in industrial applications, this chemical serves as a dielectric fluid in 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 production of carbonless copy paper and as a plasticizer in various synthetic materials. However, its use has significantly declined due to environmental and health concerns, leading to stricter regulations and phase-outs in many industries.
