This chemical is primarily used in research settings to study the environmental impact and behavior of polychlorinated biphenyls (PCBs). It serves as a reference compound in analytical chemistry for identifying and quantifying PCB contamination in soil, water, and air samples. Additionally, it is utilized in toxicology studies to understand the health effects of PCB exposure, particularly its role in bioaccumulation and potential carcinogenicity. Its application is crucial for developing remediation strategies and regulatory guidelines to mitigate PCB pollution.
