Description

(R)-(+)-2,2'-Dimethoxy-1,1'-Binaphthyl CAS NO 2960-93-2 is a high-value, enantiomerically pure chiral ligand and building block. This compound matters because its unique axially chiral binaphthyl structure is essential for inducing stereoselectivity in asymmetric synthesis. It is critically needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for applications such as asymmetric catalysis and the synthesis of chiral materials.

Application

• As a chiral ligand in asymmetric metal-catalyzed reactions, including hydrogenation, coupling, and oxidation.
• As a key precursor for synthesizing more complex chiral phosphine and diamine ligands (e.g., BINAP derivatives).
• In the asymmetric synthesis of active pharmaceutical ingredients (APIs) and agrochemical intermediates.
• For the preparation of chiral stationary phases used in high-performance liquid chromatography (HPLC) for enantiomer separation.
• As a building block in materials science for creating chiral polymers and molecular devices.
• In academic and industrial R&D for developing novel catalytic systems and synthetic methodologies.
