Description

(1R)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-Bis([1,1':3',1''-Terphenyl]-5'-Yl)-[1,1'-Binaphthalene]-2,2'-Diol is a sophisticated, chiral binaphthol derivative with a complex, sterically demanding structure. This compound matters as a high-performance ligand or catalyst precursor in asymmetric synthesis, where its rigid, three-dimensional architecture is critical for inducing high enantioselectivity in challenging transformations. It is primarily needed by research chemists and process development teams in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel synthetic routes.

Application

• As a chiral ligand in transition metal-catalyzed asymmetric reactions (e.g., hydrogenation, C-C bond formation).
• As a key building block for constructing complex molecular frameworks in pharmaceutical research.
• In the development of advanced materials, such as chiral polymers or liquid crystals.
• As a catalyst precursor for enantioselective synthesis in fine chemical production.
• For methodology development in academic and industrial organic chemistry laboratories.
• In process chemistry optimization for the scalable production of chiral intermediates.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized by advanced analytical techniques to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing specific results for chiral purity (enantiomeric excess), chemical purity, and relevant physical properties are available upon request. We support development under cGMP guidelines where required.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) to minimize oxidation and ensure long-term stability. The container should be kept in a cool, dry, and well-ventilated area.
