Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure allows for selective reactions in asymmetric synthesis, making it valuable in developing drugs with high enantiomeric purity. Commonly employed in the preparation of central nervous system agents and cardiovascular medications. Also utilized in the development of agrochemicals for creating enantioselective herbicides and pesticides. Its aromatic thiophene ring contributes to enhanced binding affinity in bioactive molecules.
