Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for facile functionalization at multiple sites, making it valuable in constructing heterocyclic compounds such as pyridines and pyrroles. Commonly employed in condensation reactions to form carbon-carbon bonds, it is especially useful in synthesizing beta-keto ester derivatives. Also applied in the development of flavor and fragrance compounds due to its reactivity and ability to form ester-based aroma chemicals.
