Description

(R)-(+)-2,2'-Dimethoxy-1,1'-Binaphthyl CAS NO 75685-01-7 is a high-purity, enantiomerically pure chiral ligand and building block of significant importance in asymmetric synthesis. Its value lies in its ability to induce chirality in catalytic reactions, enabling the production of single-enantiomer compounds with high selectivity. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require precise stereochemical control for developing active ingredients and advanced materials.

Application

• As a chiral ligand in asymmetric metal-catalyzed reactions, including hydrogenation, coupling, and oxidation.
• As a key building block for the synthesis of more complex chiral phosphine ligands (e.g., BINAP derivatives).
• In the research and development of pharmaceutical intermediates and active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• For the synthesis of chiral catalysts used in agrochemical production.
• In material science for creating chiral polymers and advanced functional materials.
• As a resolution agent or chiral selector in analytical chemistry.
