Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its halogen substituents allow selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in Suzuki and Negishi couplings to introduce aryl or alkyl groups during drug discovery processes. Also utilized in the preparation of agrochemicals and functional materials where pyrimidine scaffolds enhance performance.
