Primarily used in industrial settings, this chemical serves as a flame retardant and plasticizer in various materials, including electrical equipment and insulation. Its application extends to the production of adhesives and sealants, where it enhances durability and resistance to heat. Additionally, it has been utilized in research laboratories as a reference standard for studying environmental persistence and toxicity of polychlorinated biphenyls (PCBs). Due to its environmental and health risks, its use is now heavily regulated or banned in many regions.
