Used primarily in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of kinase inhibitors. It serves as a building block for compounds targeting inflammatory diseases, cancer, and neurological disorders. Its indazole core is valued for strong binding to enzyme active sites, enhancing drug efficacy. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic purine moieties in ATP-binding proteins. Commonly utilized in the preparation of small-molecule drug candidates during early-stage drug discovery.
