Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs and antipsychotic medications. Its structure allows for functionalization in heterocyclic compounds, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of thiophene-based derivatives that exhibit biological activity, including receptor antagonism and enzyme inhibition. Also utilized in research settings for the design of novel drug candidates due to its reactivity and ability to form stable amine derivatives.
