(S)-1-Ferrocenylethanol is primarily used in asymmetric synthesis and catalysis due to its chiral ferrocene backbone. It serves as a chiral ligand or building block in the preparation of enantioselective catalysts, particularly for transition metal-catalyzed reactions. These catalysts are employed in the production of pharmaceuticals and fine chemicals, where high enantiomeric purity is essential. Additionally, it is utilized in the development of chiral materials and sensors, leveraging its unique stereochemistry and redox properties. Its applications also extend to research in organometallic chemistry, where it aids in studying chiral induction and molecular recognition processes.
