Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of targeted cancer therapies. Its structure supports binding to specific enzyme active sites, making it valuable in creating compounds that modulate protein activity involved in tumor growth. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance metabolic stability and bioavailability in lead compounds. Additionally, it serves as a building block in the preparation of radiolabeled tracers for positron emission tomography (PET) imaging, leveraging the iodine atom for isotope substitution.
