Used primarily in industrial applications, this chemical serves as a flame retardant in various materials, including plastics and electrical equipment. It is also employed in the production of heat transfer fluids and as a dielectric fluid in transformers and capacitors. Due to its stability, it has been utilized in research settings to study the environmental impact of persistent organic pollutants. However, its use is heavily regulated because of its toxicity and potential to accumulate in the environment and living organisms. In some cases, it has been involved in environmental remediation studies to understand and mitigate the effects of polychlorinated biphenyls (PCBs) contamination.
