Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nucleoside analogs with antiviral and anticancer properties. It serves as a building block in the preparation of modified purine derivatives that can interfere with viral replication or tumor cell proliferation. Commonly employed in research settings for the design of kinase inhibitors and other biologically active compounds targeting cellular signaling pathways. Its halogen substituents allow for selective cross-coupling reactions, enabling efficient functionalization in medicinal chemistry campaigns.
