Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for selective substitution reactions, making it valuable in constructing complex heterocyclic compounds. Also employed in agrochemicals for creating herbicides and pesticides due to its ability to enhance bioactivity. Commonly utilized in research for modifying nucleoside analogs and in the preparation of functionalized pyrimidine derivatives for drug discovery.
