Used as a key intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. Its structure allows for facile functional group transformations, making it valuable in constructing complex molecules. Commonly employed in the synthesis of beta-keto ester derivatives, which serve as building blocks for drugs and agrochemicals. Also utilized in condensation reactions to form carbon-carbon bonds, especially in the development of active pharmaceutical ingredients (APIs). Its masked 1,3-dicarbonyl functionality enables controlled reactivity, useful in multi-step synthetic routes.
