Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its α,β-unsaturated carbonyl structure makes it suitable for Michael addition reactions and other conjugate additions, enabling the construction of complex molecules. Commonly employed in the synthesis of anti-inflammatory agents and heterocyclic compounds due to its reactivity and ability to form substituted derivatives. Also utilized in research settings for developing new synthetic pathways and studying reaction mechanisms involving unsaturated carboxylic acids.
