Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in creating potent bioactive molecules. Commonly employed in medicinal chemistry for constructing fused heterocyclic systems that exhibit antitumor and antiviral activities. Also utilized in research settings to develop novel drug candidates targeting specific signaling pathways in diseases like leukemia and solid tumors.
