Used primarily in research to study its effects on biological systems, particularly its role as a carcinogen. It is employed in experiments to understand the mechanisms of cancer development and the impact of polycyclic aromatic hydrocarbons on DNA. Additionally, it serves as a model compound in environmental studies to assess pollution levels and the long-term effects of exposure to hazardous substances. Its applications extend to toxicology, where it helps in evaluating the safety of various materials and in developing strategies for mitigating health risks associated with environmental contaminants.
