Used primarily as a key intermediate in organic synthesis, especially in the preparation of heterocyclic compounds and pharmaceuticals. Its conjugated structure and reactive ketone group make it suitable for cyclization reactions, including the formation of indoles and other nitrogen-containing rings. It is also employed in the development of agrochemicals and fine chemicals due to its ability to undergo nucleophilic addition and coupling reactions. Its α,β-unsaturated carbonyl system allows for Michael additions, making it valuable in the synthesis of complex molecules. Additionally, it finds use in research settings for studying reaction mechanisms involving allenes and conjugated ketones.
