Chrysene is primarily used in research and industrial applications due to its polycyclic aromatic hydrocarbon (PAH) structure. It serves as a model compound in environmental studies to understand the behavior, distribution, and degradation of PAHs in ecosystems. In the field of material science, chrysene is investigated for its potential use in organic semiconductors and optoelectronic devices, owing to its conjugated aromatic system. Additionally, it is utilized in the synthesis of dyes and pigments for specialized applications. However, due to its carcinogenic properties, its use is strictly regulated, and handling requires adherence to safety protocols to minimize exposure risks.
