Used as a key intermediate in the synthesis of pharmaceuticals, 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 bioactive molecules targeting tyrosine kinases and other enzyme families involved in signal transduction pathways. Its bromo and amino functional groups allow for sequential derivatization, making it valuable in combinatorial chemistry and drug discovery research.
