Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of fungicides and herbicides. It serves as a building block in organic reactions due to the reactivity of the nitrile group and the aromatic thiophene ring. Employed in the development of conductive polymers and organic semiconductors for electronic devices. Also utilized in the preparation of dyes and pigments, and in research for creating novel heterocyclic compounds with potential biological activity.
