This chemical is primarily used in research and environmental studies due to its presence as a persistent organic pollutant. It is often analyzed to understand the behavior, distribution, and impact of polychlorinated biphenyls (PCBs) in ecosystems. Researchers use it to study bioaccumulation and toxicity in wildlife, as well as its long-term effects on human health. It also serves as a reference compound in analytical chemistry for developing detection and quantification methods for PCBs in environmental samples. Additionally, it aids in assessing the effectiveness of remediation techniques for PCB-contaminated sites.
