Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to undergo selective cross-coupling reactions, enabling the construction of complex heterocyclic systems. Commonly employed in the preparation of antiviral agents and targeted therapies where pyrimidine derivatives play a central role. Its bromo and amino functional groups allow for sequential derivatization, making it valuable in combinatorial chemistry and drug discovery research.
