Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aryl or amino groups. Also utilized in the preparation of potential antitumor and antiviral agents due to the presence of the bromopyrimidine moiety, which can act as a leaving group or participate in nucleophilic substitution.
