Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing pyrimidine-based drug candidates. Commonly employed in cross-coupling reactions to introduce the pyrimidine moiety into larger molecules, especially in the research of anticancer and antiviral agents. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its ability to mimic nucleotide components in biochemical pathways.
