Used as a key intermediate in the synthesis of antiviral and anticancer agents due to its ability to inhibit specific kinases involved in cell proliferation. Its structure allows for strong binding to enzyme active sites, making it valuable in drug development for targeted therapies. Commonly employed in research settings to design inhibitors for protein kinases linked to tumor growth and viral replication. Also utilized in the preparation of fluorescent probes for biochemical assays because of its favorable photophysical properties.
