Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It serves as a building block in the formation of heterocyclic compounds due to its α,β-unsaturated ester structure, which readily undergoes Michael additions and cycloaddition reactions. Commonly employed in the synthesis of flavonoids, stilbenes, and other bioactive molecules with potential antioxidant or anti-inflammatory properties. Also utilized in the development of liquid crystals and nonlinear optical materials owing to its conjugated system and structural rigidity.
