Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders and anti-inflammatory agents. Its structure serves as a building block in creating biologically active molecules due to the benzothiophene core’s affinity for certain enzyme receptors. Commonly employed in medicinal chemistry for constructing more complex drug candidates. Also utilized in the preparation of specialty chemicals and functional materials where sulfur-containing heterocycles enhance electronic or optical properties.
