This chemical is primarily utilized in industrial applications, particularly in electrical equipment and heat transfer systems. It serves as a dielectric fluid in capacitors and transformers due to its stability and insulating properties. Additionally, it is used in research settings to study the environmental impact and toxicity of polychlorinated biphenyls (PCBs). Its presence is monitored in environmental samples to assess contamination levels and to develop remediation strategies. Handling requires strict safety measures due to its persistent and bioaccumulative nature.
