Used primarily in research and development, this chemical serves as a reference standard in environmental studies to detect and quantify polychlorinated biphenyls (PCBs) in various samples. It aids in understanding the distribution and persistence of PCBs in ecosystems, particularly in soil, water, and biological tissues. Additionally, it is utilized in analytical chemistry to calibrate instruments and validate methods for PCB analysis, ensuring accurate monitoring of environmental contamination. Its role is critical in assessing the impact of PCBs on human health and the environment, supporting regulatory compliance and remediation efforts.
