Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with pyrazole moieties. Its α,β-unsaturated ester structure allows for Michael addition and cycloaddition reactions, making it valuable in constructing heterocyclic compounds. Commonly employed in medicinal chemistry for building blocks in kinase inhibitors and anti-inflammatory agents. Also utilized in the preparation of novel pesticides due to the favorable electronic and steric properties imparted by the pyrazole ring.
