Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows selective modification to target specific signaling pathways in tumor cells. Commonly employed in medicinal chemistry for constructing inhibitors of tyrosine kinases and other ATP-binding site-targeted enzymes. Also utilized in the preparation of small-molecule drugs aimed at treating solid tumors and hematological malignancies. Its halogen moieties enable further functionalization via cross-coupling reactions, making it valuable in drug discovery and optimization.
