Used in organic synthesis as a building block for pharmaceuticals and natural products due to its α,β-unsaturated ester structure, which allows participation in Michael addition and cycloaddition reactions. Serves as an intermediate in the preparation of bioactive molecules, including antioxidants and anti-inflammatory agents. Also employed in the development of fragrances and flavoring agents because of its structural similarity to vanillin derivatives. Its phenolic and ester functionalities make it suitable for polymer modification and UV-absorbing materials.
