Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active compounds. Its bromo and tert-butyl functional groups allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in Suzuki and Negishi couplings to introduce the pyrimidine scaffold into target molecules. Also utilized in research settings for the preparation of fluorescent probes and functional materials due to its stable aromatic core and derivatization potential.
