Used in organic synthesis as a versatile building block for the development of complex molecules, particularly in pharmaceutical research. It serves as a key intermediate in the preparation of heterocyclic compounds, which are often explored for their potential biological activities. The presence of both bromo and iodo substituents allows for selective functionalization through cross-coupling reactions, such as Suzuki or Sonogashira couplings, enabling the creation of diverse chemical structures. Its aldehyde group also provides a reactive site for further derivatization, making it valuable in the design of drug candidates and agrochemicals. Additionally, it is employed in the synthesis of ligands for catalysis and materials science applications.
