Used primarily in scientific research as a model polycyclic aromatic hydrocarbon (PAH) to study environmental pollution and carcinogenesis. It serves as a reference compound in toxicological studies due to its known mutagenic and carcinogenic properties. Commonly employed in environmental monitoring to assess contamination from combustion processes, such as vehicle emissions, industrial activities, and tobacco smoke. Also utilized in laboratory settings to evaluate the effectiveness of remediation techniques for PAH-contaminated soil and water. Due to its stability and representative structure, it helps in understanding the behavior and fate of similar PAHs in ecosystems.
