Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for selective functionalization, making it valuable in creating pyrimidine-based drug candidates. Commonly employed in the preparation of kinase inhibitors and other biologically active molecules. Also utilized in agrochemicals for the development of herbicides and pesticides due to its ability to modulate biological pathways in target organisms. Its reactivity supports use in cross-coupling reactions and nucleophilic substitutions in medicinal chemistry research.
