Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. 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 core into larger bioactive molecules. Also utilized in agrochemical research for designing herbicides and plant growth regulators due to its ability to modulate biological activity in target organisms.
