Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the formation of nucleoside analogs, which can interfere with viral replication or disrupt cancer cell metabolism. Commonly employed in medicinal chemistry for constructing pyrimidine-based drug candidates. Also utilized in agrochemicals for designing novel pesticides due to its bioactive scaffold. Serves as a building block in combinatorial chemistry for high-throughput screening of biologically active compounds.
