Used primarily as a reactive intermediate in organic synthesis, especially in the production of pharmaceuticals and agrochemicals. Its acyl chloride group allows it to readily form esters and amides, making it valuable in constructing complex molecules. The ethoxyacryloyl structure provides both electron-donating and conjugated features, enabling use in specialty polymer synthesis and as a building block for α,β-unsaturated carbonyl compounds. It is also employed in the preparation of liquid crystals and functional materials where precise molecular architecture is required. Due to its reactivity, it is typically handled under controlled conditions and used in situ or with protective groups.
