Description

(R)-2,2'-Diamino-5,5',6,6',7,7',8,8'-Octahydro-1,1'-Binaphthyl CAS NO 208248-66-2 is a high-purity, chiral diamine derivative of octahydrobinaphthyl, serving as a sophisticated building block in asymmetric synthesis. Its rigid, three-dimensional structure and dual amino functionalities make it an exceptionally valuable chiral ligand precursor and resolving agent for creating enantiomerically pure compounds. This product is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors who require high stereoselectivity in catalytic reactions and molecular recognition.

Application

• Asymmetric Catalysis: As a precursor for chiral ligands and catalysts used in enantioselective hydrogenation, C-C bond formation, and other transition metal-catalyzed reactions.
• Pharmaceutical Intermediates: Key chiral scaffold in the synthesis of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity.
• Chiral Resolution: Employed as a resolving agent for the separation of racemic mixtures of carboxylic acids, alcohols, and other functional compounds.
• Advanced Material Synthesis: Building block for chiral polymers, liquid crystals, and metal-organic frameworks (MOFs) with specific optical or separation properties.
• Agrochemical Development: Used in the research and production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Academic & Industrial R&D: A critical tool for methodological development in organic synthesis and catalysis within university and corporate laboratories.

Quality Control

Our (R)-2,2'-Diamino-5,5',6,6',7,7',8,8'-Octahydro-1,1'-Binaphthyl is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for chiral purity and chemical assay, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing specific results for enantiomeric excess (ee), chemical purity, and identity are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
