Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of targeted cancer therapies. Its structure allows for selective binding to specific enzyme active sites, making it valuable in creating compounds that modulate cellular signaling pathways. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of reactive sites that enable further functionalization. Also utilized in radiolabeling studies owing to the iodine atom, facilitating imaging and biodistribution analysis in preclinical models.
