Used primarily as a key intermediate in organic synthesis, especially in pharmaceutical and agrochemical industries. Its strained cyclopropane ring combined with reactive functional groups enables unique ring-opening and cycloaddition reactions. It is employed in the preparation of cyclopropane-containing compounds that serve as building blocks for bioactive molecules, including certain antiviral and anti-inflammatory agents. The nitrile group allows for further transformation into carboxylic acids, amines, or tetrazoles, enhancing its utility in medicinal chemistry. Additionally, it finds use in the development of novel pesticides due to the metabolic stability imparted by the cyclopropane moiety.
