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 constructing pyrimidine-based bioactive molecules. Commonly employed in medicinal chemistry for building blocks in drug discovery programs targeting kinase inhibitors and nucleoside analogs. Also utilized in agrochemical research for developing herbicides and plant growth regulators due to its reactivity and stability in various reaction conditions.
