Used primarily as a building block in organic synthesis, especially in the development of complex cyclic compounds. Its strained ring system makes it valuable in ring-opening and rearrangement reactions. Commonly employed in pharmaceutical research to construct rigid molecular frameworks that enhance metabolic stability and binding selectivity. Also utilized in the synthesis of specialty polymers and agrochemicals where unique steric and electronic properties are required. Its ketone functionality allows for further derivatization, such as reduction, condensation, or nucleophilic addition, enabling diverse chemical transformations.
