Used as a key intermediate in organic synthesis, particularly in the preparation of cyclobutane-containing compounds which are of interest in pharmaceutical development. Its α,β-unsaturated ester structure allows for Michael additions and cycloaddition reactions, enabling the construction of complex ring systems. Commonly employed in the synthesis of bioactive molecules and analogs where the cyclobutyl moiety enhances metabolic stability and binding selectivity. Also utilized in the development of agrochemicals and specialty materials due to its rigid cyclic framework and functional versatility.
