Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its conjugated structure makes it valuable in carbon-chain elongation reactions and in forming complex aromatic ketones. Commonly employed in research settings for constructing heterocyclic compounds and as a building block in the synthesis of bioactive molecules. Also utilized in the development of dyes and functional materials due to its reactivity in cycloaddition and nucleophilic addition reactions.
