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 complex heterocyclic systems found in active drug molecules. Commonly employed in cross-coupling reactions to introduce the pyrimidine core into larger bioactive compounds. Also utilized in agrochemical research for designing new pesticides and herbicides due to its stability and reactivity profile.
