Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its conjugated ester structure makes it valuable in Michael addition reactions and cycloadditions, enabling the construction of complex nitrogen-containing molecules. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where the dimethylamino group facilitates further functionalization. Also utilized in the development of specialty polymers and as a building block in the preparation of dyes and functional materials. Its reactivity and solubility properties support its use in catalytic and solvent-free reaction systems.
