Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for effective binding in biologically active molecules, enhancing drug potency. Commonly employed in medicinal chemistry for modifying pharmacokinetic properties, such as metabolic stability and target selectivity. Also utilized in the preparation of agrochemicals and specialty polymers due to its rigid aromatic-cyclopropyl framework, which can influence material performance.
