Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its bromo and carboxylic acid functional groups allow for further chemical modifications, enabling coupling reactions and ring transformations. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to serve as a building block in heterocyclic systems. Also utilized in the preparation of selective enzyme inhibitors and receptor modulators in research settings.
