Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrimidine-based drugs such as antiviral and anticancer agents. Its structure supports the construction of nucleoside analogs, which mimic natural nucleosides and interfere with viral replication or tumor cell proliferation. Also employed in the preparation of agrochemicals and functional dyes due to its ability to form stable heterocyclic systems. Commonly utilized in research settings for building complex pyrimidine derivatives with potential biological activity.
