Used as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly in targeted cancer therapies. It plays a role in the development of pharmaceuticals that inhibit abnormal protein signaling in tumor cells, especially in treatments for thyroid and non-small cell lung cancers. Its structure allows for selective binding to mutant forms of kinase enzymes, making it valuable in precision medicine. Also utilized in research settings to design analogs with improved bioavailability and potency.
