Description

1,1'-Binaphthyl-2,2'-Diamine is a high-purity, axially chiral diamine compound, serving as a critical building block in advanced organic synthesis. Its value lies in its rigid, non-racemic structure, which is essential for creating chiral ligands, catalysts, and functional materials. This product is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and material science sectors for developing enantioselective processes and optoelectronic components.

Application

• Chiral Ligand & Catalyst Synthesis: A key precursor for BINOL- and BINAP-type ligands used in asymmetric hydrogenation and cross-coupling reactions.
• Pharmaceutical Intermediates: Employed in the research and development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity.
• Advanced Material Science: Used in the synthesis of chiral polymers, liquid crystals, and molecular recognition systems for sensors.
• Agrochemical Research: Serves as a building block for developing novel, enantiomerically pure herbicides and fungicides.
• Supramolecular Chemistry: Acts as a fundamental unit for constructing complex chiral host molecules and frameworks.

Quality Control

Our 1,1'-Binaphthyl-2,2'-Diamine is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive analytical data, including chiral purity (enantiomeric excess) and standard impurity profiles. Certificates of Analysis (COA) documenting identity, assay, and purity are available for every batch 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
