Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports modification for targeted drug design, especially in nucleoside analogs. Also employed in agrochemical research for creating novel pesticides and herbicides due to its ability to interfere with metabolic pathways in pathogens and pests. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving pyrimidine-based compounds.
