Used primarily in pharmaceutical research and development as a building block for the synthesis of complex molecules. It serves as an intermediate in the production of various active pharmaceutical ingredients (APIs), particularly those targeting therapeutic areas such as oncology and infectious diseases. Its pyrimidine core structure is valuable in designing compounds with potential biological activity. Additionally, it is employed in organic synthesis for creating heterocyclic compounds, which are essential in drug discovery and material science. The bromo group allows for further functionalization, making it a versatile reagent in chemical transformations.
