Used primarily in research settings to study the effects of polycyclic aromatic hydrocarbons (PAHs) on biological systems. It serves as a model compound for investigating carcinogenesis, as it is known to induce tumors in laboratory animals. This chemical is also utilized in environmental studies to assess the impact of PAHs released from combustion processes, such as vehicle emissions and industrial activities. Additionally, it helps in developing and testing methods for detecting and quantifying PAHs in air, water, and soil samples to monitor pollution levels.
