Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for heterocyclic compounds due to the presence of reactive functional groups—the bromo, keto, and ester moieties—which allow for selective transformations such as nucleophilic substitution, condensation, and cyclization reactions. Commonly employed in the synthesis of alpha-amino acids, peptides, and bioactive molecules where controlled functionalization is required. Its reactivity profile makes it valuable in medicinal chemistry for constructing complex molecular architectures.
