Used as a key intermediate in the synthesis of kinase inhibitors, particularly in anticancer drug development. It serves as a scaffold in targeted therapies, especially for tyrosine kinase and cyclin-dependent kinase inhibitors. Its structure allows selective binding to ATP sites in enzymes involved in cell proliferation, making it valuable in designing drugs for leukemia, melanoma, and other cancers. Also explored in antiviral research due to its potential to interfere with viral replication pathways.
