Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. It plays a role in the development of compounds that modulate cell signaling pathways involved in tumor growth and proliferation. Its structure allows for selective binding to specific enzyme active sites, making it valuable in designing drugs with high specificity and reduced side effects. Also explored in the creation of antiviral agents due to its ability to interfere with viral replication enzymes.
