Used primarily as an intermediate in the production of hydrogen peroxide through the anthraquinone process. In this method, it undergoes hydrogenation to form 2-ethylanthrahydroquinone, which is then oxidized back to regenerate the original compound while producing hydrogen peroxide. This process is widely employed in industrial settings due to its efficiency and scalability. Additionally, it finds limited use in organic synthesis and research applications, particularly in studies involving redox reactions and catalytic processes. Its role in hydrogen peroxide production makes it a key component in industries such as paper bleaching, chemical manufacturing, and water treatment.
