Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. Its halogen substituents allow for selective cross-coupling reactions, making it valuable in constructing complex organic molecules. Commonly employed in palladium-catalyzed reactions such as Suzuki and Heck couplings to introduce pyrimidine scaffolds into target compounds. Also utilized in the preparation of kinase inhibitors and other biologically active molecules in medicinal chemistry research.
