Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical industry. It serves as a building block for more complex molecules due to the reactivity of the naphthalene ring and the steric influence of the cyclopropyl group. Commonly employed in the development of bioactive compounds, including potential antiviral and anticancer agents. Its rigid structure makes it valuable in medicinal chemistry for modulating metabolic stability and binding affinity. Also utilized in research settings to study reaction mechanisms involving strained ring systems.
