Used as an 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 participate in cross-coupling reactions, enabling the construction of complex heterocyclic systems. Commonly employed in the preparation of biologically active molecules targeting tyrosine kinases and other enzyme families involved in signal transduction pathways. Its bromo and carboxylic acid functional groups allow for further derivatization, making it valuable in structure-activity relationship (SAR) studies during drug discovery.
