Used as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals. Its structure allows for the introduction of difluoro motifs and ester functionalities, which are valuable in enhancing metabolic stability and bioavailability in drug design. Commonly employed in condensation and cyclization reactions to build heterocyclic systems such as pyrazoles and isoxazoles. Also applied in the development of novel fluorinated building blocks for medicinal chemistry research.
