Used as a key intermediate in organic synthesis, particularly in the development of pharmaceuticals and fine chemicals. Its strained bicyclic structure and reactive aldehyde group make it valuable for constructing complex molecular frameworks through cycloadditions, nucleophilic additions, and ring-opening reactions. Commonly employed in the synthesis of bioactive compounds, including antiviral and anticancer agents, due to its ability to introduce rigidity and stereochemical control in target molecules. Also utilized in materials science for building functionalized polymers and specialty monomers with tailored properties.
