Description

S-1,1'-Binaphthyl-2,2'-Dicarboxylic Acid is a high-value, enantiomerically pure chiral building block and ligand precursor. This compound is essential for the synthesis of advanced asymmetric catalysts and functional materials due to its rigid, axially chiral binaphthyl scaffold. It is primarily utilized by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for developing novel chiral compounds and catalysts.

Application

• Key chiral intermediate in the synthesis of pharmaceutical active ingredients (APIs), particularly for enantioselective drugs.
• Precursor for constructing BINOL-based chiral ligands and catalysts used in asymmetric synthesis (e.g., hydrogenation, coupling reactions).
• Building block for functional polymers and advanced organic materials with specific optical or electronic properties.
• Starting material for the preparation of chiral metal-organic frameworks (MOFs) and supramolecular structures.
• Use in analytical chemistry as a chiral selector or stationary phase modifier in chromatography.
• Research and development of novel asymmetric catalytic systems in academic and industrial laboratories.
