Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds. It serves as a building block in the development of kinase inhibitors, which are important in cancer therapy and inflammatory disease treatment. Its bromo and indazole structure allows for further functionalization through cross-coupling reactions, making it valuable in medicinal chemistry for creating compound libraries. Also utilized in the study of receptor binding and signal transduction pathways due to its ability to mimic purine moieties in nucleotides.
