This chemical is primarily used in industrial applications, particularly as a dielectric fluid in electrical equipment like transformers and capacitors due to its insulating properties. It helps in stabilizing electrical systems by preventing short circuits and ensuring efficient energy transfer. Additionally, it has been utilized in heat transfer systems and as a plasticizer in certain manufacturing processes to enhance material flexibility. However, its use has significantly declined due to environmental and health concerns, leading to stricter regulations and the development of safer alternatives.
