Cyclopropylbenzene is primarily used as an intermediate in the synthesis of various pharmaceuticals and organic compounds. Its unique structure makes it valuable in the production of drugs, particularly those targeting central nervous system disorders. Additionally, it serves as a building block in the development of agrochemicals, including pesticides and herbicides, due to its stability and reactivity. In research, cyclopropylbenzene is employed in organic chemistry studies to explore ring-opening reactions and other cyclopropane-related transformations. Its applications also extend to the field of material science, where it is used in the synthesis of specialty polymers and advanced materials.
