Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor ligands and other bioactive heterocyclic compounds. It serves as a building block in the preparation of pyridine and pyrimidine derivatives, which are important in drug development for neurological and inflammatory conditions. Its α,β-unsaturated carbonyl structure allows for selective Michael additions and cyclization reactions, making it valuable in medicinal chemistry research. Also employed in the development of dyes and functional organic materials due to its conjugated system and reactivity.
