Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients that require substituted thiophene scaffolds. Its functional groups—bromo, cyano, and ester—allow for selective transformations such as cross-coupling reactions, nucleophilic substitutions, and hydrolysis, enabling the construction of complex molecules. Commonly employed in medicinal chemistry for the preparation of kinase inhibitors and other biologically active compounds. Also utilized in the manufacture of specialty chemicals and functional materials where aromatic heterocycles with electron-withdrawing groups are needed.
