Used primarily in research settings to study the effects of polycyclic aromatic hydrocarbons (PAHs) on biological systems. It serves as a model compound to investigate the mechanisms of carcinogenesis and mutagenesis, particularly in understanding how PAHs interact with DNA and induce mutations. Additionally, it is employed in environmental studies to assess the impact of PAH contamination in air, water, and soil, helping to develop strategies for pollution control and remediation. Its role in toxicology studies aids in evaluating the health risks associated with exposure to similar compounds.
