Used primarily in research and industrial settings, this chemical serves as a reference standard in environmental analysis to detect and quantify polychlorinated biphenyls (PCBs) in various samples. It aids in studying the distribution, persistence, and ecological impact of PCBs in ecosystems. Additionally, it is utilized in toxicology studies to assess the health risks associated with PCB exposure, particularly their effects on the immune, nervous, and endocrine systems. Its role in understanding PCB degradation and remediation strategies is also significant in environmental science.
