Used as a key intermediate in the synthesis of antiviral and anticancer agents, particularly in the development of nucleoside analogs. Its structure mimics natural pyrimidine bases, allowing incorporation into nucleic acid chains to inhibit viral replication or tumor cell proliferation. Commonly employed in medicinal chemistry for designing drugs targeting HIV, hepatitis, and other viral infections. Also explored in kinase inhibitor formulations for targeted cancer therapy. Shows stability under physiological conditions, making it suitable for oral drug formulations.
