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 constructing active pharmaceutical ingredients (APIs) with high potency. Commonly employed in cross-coupling reactions to introduce the pyrimidine core into larger drug-like molecules. Also utilized in agrochemical research for designing novel pesticides due to its electron-deficient aromatic system that enhances binding to biological targets.
