Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antipsychotic and antihypertensive drugs. It serves as a building block in the preparation of thiophene-based heterocyclic compounds, which are important in medicinal chemistry due to their biological activity. Also applied in the production of agrochemicals and dyes, where its aldehyde and amine functional groups allow for diverse chemical modifications. Its structure supports conjugation in organic semiconductors, making it useful in some electronic materials research.
