Used primarily in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly those targeting tyrosine kinases involved in cancer cell proliferation. Its structure enables selective binding to enzyme active sites, making it valuable in developing targeted therapies for oncology. It has shown utility in the preparation of compounds with activity against resistant strains of kinases, improving drug efficacy in refractory cancers. Additionally, its derivatives are explored for anti-inflammatory and antiviral applications due to their modulation of cellular signaling pathways.
