Used primarily in environmental and toxicological research, this chemical serves as a reference standard for studying the behavior, distribution, and effects of polychlorinated biphenyls (PCBs) in ecosystems. It helps in analyzing PCB contamination in soil, water, and air, as well as assessing their bioaccumulation in organisms. Additionally, it aids in developing and validating analytical methods for detecting PCBs in various environmental samples. Its use in octane as a solvent ensures stability and precise measurements in laboratory settings.
