Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building active ingredients in drug discovery. Also employed in agrochemicals to create herbicides and pesticides due to its ability to interfere with metabolic pathways in pests and weeds. Commonly utilized in research settings for designing novel pyrimidine-based compounds with biological activity.
