Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral and anticancer agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for designing inhibitors targeting specific enzymes. Commonly employed in research settings to construct biologically active molecules, especially those involving kinase inhibition or nucleoside analogs. Also utilized in the preparation of labeled compounds for metabolic studies due to the presence of iodine, which facilitates radiolabeling or imaging applications.
