Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of kinase inhibitors and anti-inflammatory agents. Its spirocyclic structure enhances binding selectivity to enzyme active sites, improving drug efficacy. Also employed in the design of fluorescent probes for cellular imaging due to its electron-withdrawing cyano and ester groups that support conjugation and signal detection. Shows potential in agrochemical formulations for targeted pest control owing to its metabolic stability and lipophilic character.
