Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly those targeting cancer-related enzymes such as mTOR and PI3K. Its structure supports high binding affinity to ATP-binding sites in kinases, making it valuable in developing targeted therapies. Also employed in the creation of bioactive probes for studying cellular signaling pathways. Commonly found in early-stage drug discovery for optimizing lead compounds due to its favorable solubility and stability profile.
