Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. Its α,β-unsaturated ester structure makes it suitable for Michael addition reactions and other conjugate additions, enabling the construction of complex organic molecules. Commonly employed in the development of active ingredients in crop protection agents due to its reactivity and ability to form carbon-carbon bonds. Also utilized in research settings for the preparation of liquid crystals and functional materials where aromatic and olefinic moieties are required. Its (E)-configuration ensures predictable stereochemistry in downstream reactions, which is critical in drug design and development.
