6-Aminochrysene is primarily used in research settings as a model compound to study the metabolic activation and DNA adduct formation of polycyclic aromatic hydrocarbons (PAHs). It serves as a tool to investigate the mechanisms of chemical carcinogenesis, particularly in understanding how PAHs induce mutations and cancer. Additionally, it is utilized in biochemical studies to explore the role of enzymes like cytochrome P450 in the metabolic processing of carcinogens. Its fluorescence properties also make it useful in spectroscopic studies for detecting and analyzing PAH derivatives in environmental and biological samples.
