This compound is primarily used in organic synthesis as an intermediate for the preparation of more complex molecules. It features an aldehyde group at the 4-position of the pyridine ring, which is highly reactive for nucleophilic additions and other transformations. It is particularly valuable in pharmaceutical research, where it serves as a building block for the development of active pharmaceutical ingredients (APIs). The Boc (tert-butoxycarbonyl) protecting group allows for selective reactions at other functional sites, making it useful in peptide synthesis and the creation of heterocyclic compounds. Additionally, the bromo substituent enables further functionalization through cross-coupling reactions, such as Suzuki or Sonogashira couplings, which are essential in drug discovery and material science. Its application extends to the synthesis of ligands for catalysis and the development of novel bioactive compounds.
