Description

(R)-3,3'-Bis(3,5-Diisopropylphenyl)-[1,1'-Binapthalene]-2,2'-Diol CAS NO 1435948-31-4 is a high-value, chiral binaphthol derivative widely recognized as a privileged ligand and catalyst precursor in asymmetric synthesis. Its core value lies in its ability to induce high enantioselectivity in a variety of organic transformations, enabling the production of single-enantiomer compounds critical for advanced materials and pharmaceuticals. This product is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty fine chemical industries who require reliable, high-purity chiral auxiliaries to develop novel active ingredients and high-performance materials.

Application

• Asymmetric Catalysis: Serving as a key ligand for transition metals (e.g., Rh, Ru, Pd) in enantioselective hydrogenation, C-C bond formation, and oxidation reactions.
• Pharmaceutical Intermediate Synthesis: Critical for constructing chiral centers in the development of active pharmaceutical ingredients (APIs) and drug candidates.
• Agrochemical Production: Used in the synthesis of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Material Science: Employed in the development of chiral polymers, liquid crystals, and molecular recognition systems.
• Academic & Industrial R&D: A fundamental tool for methodological development in organic chemistry and process optimization in pilot plants.
• Chiral Resolution: Can be utilized in the preparation of chiral stationary phases for analytical or preparative chromatography.
