Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of pyrimidine-based bioactive molecules. Its halogen substituents allow selective cross-coupling reactions, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for the preparation of kinase inhibitors and antiviral agents. Also utilized in materials science for the design of organic semiconductors and functionalized polymers through palladium-catalyzed coupling reactions.
