Used as a key intermediate in organic synthesis, particularly in the preparation of nitrogen-containing heterocyclic compounds. Its α,β-unsaturated ester structure with an acetamido group enables participation in Michael additions and cyclocondensation reactions, making it valuable for constructing pyrroles, pyridines, and other bioactive ring systems. Commonly employed in pharmaceutical research for developing kinase inhibitors and anti-inflammatory agents. Also utilized in the synthesis of agrochemicals and functional dyes due to its conjugated system and reactivity toward nucleophiles.
