Used primarily in research settings as a metabolic intermediate in the study of polycyclic aromatic hydrocarbon (PAH) metabolism. It serves as a model compound for investigating enzymatic oxidation and detoxification pathways, particularly those involving cytochrome P450 enzymes. Due to its structural similarity to carcinogenic PAHs, it is also employed in toxicological studies to assess DNA adduct formation and cellular mutagenicity. Its fluorescence properties make it useful in spectroscopic studies examining molecular interactions in biological systems. Not used in commercial or industrial applications due to its toxicity and research-specific nature.
