Used as a key intermediate in the synthesis of pharmaceutical agents, particularly kinase inhibitors. It plays a role in the development of targeted cancer therapies due to its ability to selectively modify enzyme activity involved in cell signaling pathways. Its structure enables binding to specific ATP sites in kinases, making it valuable in creating drugs for treating cancers such as melanoma and non-small cell lung carcinoma. Also employed in research settings to design novel compounds with improved potency and selectivity.
