Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure enables selective binding to enzyme targets involved in cell signaling pathways. Commonly utilized in research and development of targeted therapies for oncology, especially in compounds aimed at treating solid tumors and hematological malignancies. Also employed in the preparation of active pharmaceutical ingredients (APIs) requiring fused heterocyclic scaffolds for enhanced biological activity and metabolic stability.
