Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and anticancer agents. Its structure allows for selective functionalization, making it valuable in developing nucleoside analogs. Also employed in agrochemicals for the creation of herbicides and plant growth regulators due to its ability to interfere with metabolic pathways in pests and weeds. Additionally, it serves as a building block in the preparation of dyes and functional materials where halogenated pyrimidines enhance stability and reactivity.
