Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its structure allows for easy functionalization, making it valuable in constructing complex molecules through carbon-chain elongation or cyclization reactions. Commonly employed in the synthesis of beta-keto esters and other malonate derivatives, it plays a role in creating active ingredients in drugs targeting inflammation and central nervous system disorders. Also utilized in the development of specialty polymers and fine chemicals due to its reactivity in Michael additions and alkylation reactions.
