Application

1-Benzo(b)thien-2-ylethan-1-one is widely utilized as a key building block in the synthesis of pharmacologically active compounds, particularly in the development of benzothiophene-based drug candidates. It serves as a precursor for functionalized heterocycles in materials science, including organic semiconductors and luminescent materials. Researchers also employ this compound in studying structure-activity relationships (SAR) due to its rigid aromatic framework and reactive ketone moiety.
