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 building complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to introduce pyrimidine motifs in drug candidates. Also utilized in agrochemical research for designing novel pesticides with improved activity and selectivity.
