Used as a chiral ligand or building block in asymmetric synthesis, enabling the formation of stereoselective compounds in pharmaceutical and fine chemical manufacturing. Its rigid, bulky structure supports the development of catalysts for enantioselective reactions. Also employed in the preparation of organic electronic materials and as a precursor in the synthesis of tetraphenylethylene derivatives, which exhibit aggregation-induced emission properties useful in optoelectronic devices and fluorescent sensors.
