Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. Its structure allows for the introduction of thiophene-based motifs, which are common in drugs targeting neurological disorders. It is also employed in the preparation of agrochemicals and specialty polymers due to its reactivity and ability to form stable derivatives. The amine group enables coupling reactions, making it valuable in medicinal chemistry for building complex molecules through amide or sulfonamide bond formation.
