Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of heterocyclic compounds. Its functional groups—cyano, bromo, and aldehyde—allow for diverse chemical transformations, such as cross-coupling reactions, nucleophilic substitutions, and condensation reactions. Commonly employed in the preparation of benzoxazoles, benzimidazoles, and other nitrogen-containing fused rings with biological activity. Also utilized in the manufacture of dyes and functional materials due to its electron-withdrawing substituents and reactivity profile.
