Used in organic synthesis as a key intermediate for pharmaceuticals and agrochemicals. Its α,β-unsaturated ester structure allows participation in Michael additions and cycloaddition reactions, facilitating the construction of nitrogen-containing heterocycles. Commonly employed in the development of kinase inhibitors and other bioactive molecules due to the pyridine moiety’s favorable binding properties. Also applied in materials science for synthesizing functional polymers with optoelectronic properties.
