Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and anticancer agents. It serves as a building block in the development of nucleoside analogs, which mimic natural nucleosides and interfere with viral replication or tumor growth. Also employed in the preparation of agrochemicals and functional materials due to its ability to form stable heterocyclic structures. Its hydroxyl group allows for easy modification, enabling the creation of diverse derivatives for drug discovery and material science applications.
