Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and biologically active compounds. Its α,β-unsaturated carbonyl structure allows participation in Michael addition reactions, making it valuable for constructing carbon-carbon bonds. Commonly employed in the preparation of peptidomimetics and enzyme inhibitors due to its ability to mimic peptide bonds and interact with biological targets. Also utilized in the synthesis of heterocyclic compounds for medicinal chemistry research.
