Primarily used in research and environmental studies to understand the behavior and impact of polychlorinated biphenyls (PCBs) in ecosystems. It serves as a reference compound for analyzing PCB contamination in soil, water, and air. Due to its persistence and toxicity, it is studied to assess its effects on wildlife and human health, particularly its potential to disrupt endocrine systems and cause long-term environmental damage. It is also used in the development of remediation techniques to mitigate PCB pollution in contaminated sites.
