Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its α,β-unsaturated carboxylic acid structure makes it suitable for Michael addition reactions and conjugate additions, commonly employed in the development of bioactive molecules. Frequently utilized in the preparation of stilbene derivatives, which show potential in medicinal chemistry due to their antioxidant, anti-inflammatory, and anticancer properties. Also serves as a building block in the synthesis of liquid crystals and nonlinear optical materials owing to its rigid aromatic framework and extended π-conjugation. The benzyl-protected phenolic group allows for selective deprotection, enabling stepwise synthesis in complex molecule assembly.
