Used as a key intermediate in organic synthesis, particularly in the preparation of flavonoids and chalcone derivatives, which exhibit biological activities such as anti-inflammatory, antimicrobial, and anticancer properties. It serves as a building block in the synthesis of heterocyclic compounds, including pyrazoles and isoxazoles, due to the reactivity of its conjugated carbonyl and ester functionalities. Its α,β-unsaturated structure allows participation in Michael addition reactions, making it valuable in the development of pharmaceuticals and agrochemicals. Also employed in the fabrication of dyes and UV absorbers owing to its extended π-conjugation system.
