Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its α-bromo ketoester structure makes it valuable for introducing functionalized side chains in heterocyclic compounds. Commonly employed in condensation reactions to build complex molecules, including active pharmaceutical ingredients (APIs). Also utilized in the synthesis of α-substituted carbonyl compounds through nucleophilic substitution or metal-catalyzed coupling reactions. Its reactivity allows for easy modification in multi-step synthetic pathways.
