This chemical is primarily used in scientific research to study the environmental impact and behavior of polychlorinated biphenyls (PCBs). It serves as a reference standard in analytical chemistry to identify and quantify PCB contamination in environmental samples such as soil, water, and air. Due to its persistence and bioaccumulative nature, it is also used in toxicological studies to assess its effects on human health and ecosystems. Additionally, it aids in understanding the degradation pathways and long-term environmental fate of similar PCB compounds. Its application is strictly limited to controlled laboratory settings due to its hazardous nature.
