Description

2,2'-Binaphthalene-6,6'-Dicarboxylic Acid is a high-purity, axially chiral dicarboxylic acid derivative that serves as a critical building block in advanced organic synthesis. Its rigid, binaphthyl backbone makes it an invaluable precursor for constructing sophisticated ligands, catalysts, and functional materials. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for applications requiring precise stereochemical control and molecular recognition.

Application

• Chiral Ligand Synthesis: A key precursor for the preparation of BINOL and BINAP-type ligands used in asymmetric catalysis.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) where chirality is crucial for biological activity.
• Metal-Organic Frameworks (MOFs): Serves as a functionalized organic linker for constructing porous coordination polymers with specific catalytic or adsorption properties.
• Functional Polymer Monomer: Used to create polymers with unique optical, electronic, or mechanical characteristics due to its rigid, conjugated structure.
• Analytical Chemistry: Acts as a chiral selector or stationary phase modifier in chromatography for enantiomer separation.
• Agrochemical Research: Utilized in developing novel, stereoselective pesticides and herbicides.

Quality Control

Our 2,2'-Binaphthalene-6,6'-Dicarboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral purity assessment, to ensure it meets the high standards required for research and production. Certificates of Analysis (COA) detailing specific batch results are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which may affect stability and performance.
