Used primarily in research and development, particularly in the study of polycyclic aromatic hydrocarbons (PAHs) and their environmental impact. It serves as a reference compound in analytical chemistry for identifying and quantifying similar substances in environmental samples. Additionally, it is utilized in the synthesis of more complex organic molecules, aiding in the exploration of chemical reactions and pathways. Its properties make it valuable in toxicology studies to understand the effects of chlorinated PAHs on biological systems.
