Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. Its keto-ester functionality allows for versatile reactivity, particularly in condensation and cyclization reactions. Commonly employed in the preparation of heterocyclic compounds, including pyrazoles and isoxazoles, which are core structures in many bioactive molecules. Also utilized in the manufacture of specialty polymers and as a building block in fine chemical synthesis due to its ability to undergo selective reductions and alkylations.
