Used in the synthesis of antiviral and anticancer agents due to its pyrimidine backbone, which can interfere with nucleic acid metabolism. Acts as a key intermediate in developing pharmaceuticals, particularly in creating nucleoside analogs. Also employed in the preparation of dyes and functional materials because of its sulfur and nitrogen-containing structure, which supports metal coordination and catalytic properties. Shows potential in biochemical research for probing enzyme activity, especially in kinases and transferases.
