Description

1,1'-Binaphthyl-8,8'-Dicarboxylic Acid is a high-purity, axially chiral dicarboxylic acid derivative that serves as a sophisticated building block in advanced organic synthesis. Its rigid, V-shaped binaphthyl core makes it an invaluable precursor for constructing chiral ligands, metal-organic frameworks (MOFs), and functional polymers. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries who require precise molecular architectures for catalysis and advanced material development.

Application

• Chiral Ligand Synthesis: A key precursor for synthesizing BINOL and BINAP-type ligands used in asymmetric catalysis for pharmaceutical intermediates.
• Metal-Organic Frameworks (MOFs): Acts as a functionalized organic linker to create porous, chiral MOFs for gas storage, separation, and sensing applications.
• Functional Polymer Backbone: Incorporated into polyimides and polyesters to impart rigidity, thermal stability, and optical activity to high-performance polymers.
• Pharmaceutical Research: Used in the development of novel active pharmaceutical ingredients (APIs) where chirality is critical for biological activity.
• Supramolecular Chemistry: Serves as a building block for constructing complex, self-assembled molecular systems and host-guest complexes.
• Analytical Chiral Stationary Phases: Can be derivatized for use in HPLC columns to separate enantiomers.
• Agrochemical Intermediates: Employed in the synthesis of chiral herbicides and fungicides.
• Optoelectronic Materials: A candidate material for organic light-emitting diodes (OLEDs) and nonlinear optical (NLO) applications due to its extended conjugated system.

Quality Control

Our 1,1'-Binaphthyl-8,8'-Dicarboxylic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high chemical purity and chiral integrity, meeting the stringent requirements for research and fine chemical synthesis. Certificates of Analysis (COA) detailing purity, chiral purity (enantiomeric excess), and impurity profiles are available upon request. We can support development projects with custom purity grades and analytical method development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants or an inert atmosphere.
