Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting tyrosine kinases involved in cancer signaling pathways. Its structure enables selective binding and modulation of enzyme activity, making it valuable in developing targeted therapies for oncology. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity. Also utilized in radiolabeling studies due to the presence of iodine, allowing for imaging and biodistribution analysis in preclinical models.
