Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its halogenated structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in Suzuki and Buchwald–Hartwig reactions to introduce pyrimidine scaffolds into drug candidates. Also utilized in agrochemical research for designing bioactive molecules with improved stability and target specificity.
