Used primarily as a key intermediate in the synthesis of pharmaceuticals, especially in the development of fluorinated and iodinated organic compounds. Its structure allows for selective functionalization in drug molecules, enhancing metabolic stability and binding affinity. Commonly employed in radiolabeling applications due to the presence of iodine, enabling use in imaging agents or tracer studies. The fluorine atom also supports improved bioavailability in final active compounds, making it valuable in medicinal chemistry for creating targeted therapies, particularly in oncology and neurology research.
