Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and anticancer agents. Its structure allows for selective modification, making it valuable in medicinal chemistry for designing drugs that target specific signaling pathways. Commonly employed in research settings to develop potential treatments for solid tumors and inflammatory diseases. Also utilized in the preparation of fluorescent probes due to its heterocyclic framework, aiding in cellular imaging and biochemical assays.
