Description

S-2,2'-Dihydroxy-[1,1'-Binaphthalene]-3,3'-Dicarboxaldehyde is a high-purity, enantiomerically pure binaphthyl derivative that serves as a critical chiral building block and ligand precursor in advanced organic synthesis. Its value lies in its rigid, axially chiral structure, which is essential for inducing stereoselectivity in catalytic reactions and constructing complex molecular architectures. This compound is primarily needed by research institutions and pharmaceutical companies engaged in asymmetric catalysis, materials science, and the development of novel chiral sensors or pharmaceuticals.

Application

• Asymmetric Catalysis: As a precursor for synthesizing chiral ligands (e.g., BINOL derivatives) used in metal-catalyzed enantioselective reactions such as hydrogenation, oxidation, and C-C bond formation.
• Pharmaceutical Intermediates: A key starting material for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs) and complex natural products.
• Chiral Materials: Used in the development of chiral stationary phases for HPLC, circularly polarized luminescence materials, and molecular recognition systems.
• Organic Synthesis: Acts as a versatile scaffold for constructing complex polycyclic aromatic compounds and macrocycles with defined chirality.
• Sensor Development: Employed in the design of chiral fluorescent sensors and probes for the detection of specific ions or small molecules.
