Used primarily in environmental research and analytical chemistry, this chemical serves as a standard reference material for the detection and quantification of polychlorinated biphenyls (PCBs) in various samples. It is instrumental in calibrating instruments like gas chromatographs and mass spectrometers, ensuring accurate measurement of PCB contamination in soil, water, and air. Additionally, it aids in studying the environmental persistence, distribution, and toxicological impact of PCBs, contributing to regulatory compliance and pollution control efforts.
