Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules that require halogenated pyrazine scaffolds. Its bromo and trifluoromethyl functional groups allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Commonly employed in the preparation of kinase inhibitors and antimicrobial agents. Also utilized in materials science for designing electron-deficient aromatic systems in organic semiconductors.
