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 research settings for drug discovery targeting tyrosine kinase pathways. Also utilized in the preparation of fluorescent probes due to its electron-withdrawing nitrile group and heterocyclic framework, enabling applications in biochemical imaging and diagnostics.
