Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of receptor antagonists and enzyme inhibitors. Its structure supports the formation of bioactive molecules, especially in research targeting inflammatory and neurological disorders. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems due to the reactivity of the carboxylic acid and halogen groups, enabling coupling reactions and derivatization. Also utilized in the preparation of agrochemicals and functional materials where halogenated thiophene derivatives enhance electronic or stability properties.
