No known practical applications exist for 8-hydroxybenzopyrene due to its status as a metabolite of benzo[a]pyrene, a toxic and carcinogenic polycyclic aromatic hydrocarbon. It forms in the body during the metabolic breakdown of benzo[a]pyrene, primarily in the liver, through cytochrome P450 enzyme activity. Its presence is associated with oxidative stress and DNA damage, making it a biomarker for exposure to polycyclic aromatic hydrocarbons in environmental and occupational health studies. Research focuses on its role in toxicology and cancer risk assessment rather than industrial or commercial use.
