Used primarily in research and development settings to study the environmental impact and behavior of polychlorinated biphenyls (PCBs). It serves as a model compound to understand the degradation, persistence, and toxicological effects of PCBs in ecosystems. Additionally, it is utilized in the development of analytical methods for detecting and quantifying PCB contamination in environmental samples such as soil, water, and air. Its application also extends to assessing the effectiveness of remediation techniques aimed at reducing PCB pollution.
