Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective cross-coupling reactions, making it valuable in constructing complex heterocyclic systems found in drug candidates. Commonly employed in Suzuki and Buchwald–Hartwig reactions to introduce pyrimidine moieties into target molecules. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its ability to modulate biological activity in specific molecular frameworks.
