Description

(R)-3,3'-Bis(4-Methoxyphenyl)-[1,1'-Binaphthalene]-2,2'-Diol is a high-value, enantiomerically pure binaphthol derivative, widely recognized as a privileged chiral ligand and catalyst precursor in asymmetric synthesis. Its core value lies in its ability to induce high enantioselectivity in a variety of organic transformations, making it indispensable for producing optically active intermediates. This compound is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where precise stereochemical control is critical for product efficacy and performance.

Application

• As a chiral ligand in transition metal-catalyzed asymmetric reactions, including hydrogenation, coupling, and addition reactions.
• As a key building block for the synthesis of complex, enantiomerically pure pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
• In the development of chiral catalysts and organocatalysts for fine chemical and agrochemical production.
• For the preparation of chiral stationary phases (CSPs) used in high-performance liquid chromatography (HPLC) for enantiomer separation.
• As a molecular scaffold in supramolecular chemistry and the design of functional materials with chiral properties.
• In academic and industrial R&D for exploring novel asymmetric synthetic methodologies.
