Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure, featuring a bromine at the activated 2-position of the pyrimidine ring, enables selective nucleophilic aromatic substitution (SNAr) and cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki and Negishi couplings to form carbon-carbon bonds in drug discovery pipelines. Also utilized in agrochemical research for designing new active ingredients in crop protection products.
