Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective modification to target specific protein kinases involved in tumor growth and proliferation. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of multiple reactive sites, enabling the introduction of various functional groups. Also utilized in the preparation of small molecule therapeutics targeting inflammatory diseases and viral infections. Its halogen substitutions facilitate cross-coupling reactions, making it valuable in combinatorial chemistry and drug discovery pipelines.
