Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its strained cyclobutane ring and reactive exocyclic double bond make it valuable in cycloaddition reactions, including [2+2] and Diels-Alder reactions, enabling the construction of complex cyclic and polycyclic structures. Commonly employed in the development of bioactive molecules, such as enzyme inhibitors and receptor modulators, due to its ability to mimic specific conformational motifs. Also utilized in polymer chemistry to introduce rigidity and unique structural features into polymer backbones.
