Used as a key intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its cyclic structure and reactive carbonyl groups make it valuable for constructing complex heterocyclic systems. Commonly employed in Michael addition reactions and cycloadditions to build bioactive molecules. Also utilized in the preparation of functionalized pyrrolidones, which show activity in central nervous system agents and enzyme inhibitors. Its derivatives are explored for potential antitumor and antimicrobial properties.
