This chiral phosphoric acid derivative is primarily employed as a Brønsted acid catalyst in asymmetric organocatalysis, facilitating enantioselective reactions including aza-Mannich, Pictet-Spengler, and other carbon-carbon or carbon-heteroatom bond formations. Its distinctive (S)-binaphthyl backbone with 3,3'-anthracenyl substituents enhances stereoselectivity and catalytic efficiency. Furthermore, it serves in the synthesis of chiral stationary phases for high-performance liquid chromatography (HPLC), supporting enantiomer separation in pharmaceutical and fine chemical research. The fluorescent anthracene groups enable applications in molecular recognition and chemosensing studies.
