Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its α,β-unsaturated ester structure makes it suitable for Michael addition reactions and other conjugate additions, enabling the construction of complex molecules. Commonly employed in the development of bioactive compounds, including anti-inflammatory and anticancer agents. Also utilized in the synthesis of liquid crystals and functional polymers due to its rigid aromatic core and reactive vinyl group. Its methoxyphenyl moiety enhances electron-donating properties, beneficial in materials science for tuning optical and electronic characteristics.
