Description

[1,1'-Binaphthalene]-5,5'-Dicarboxylic Acid is a high-purity, axially chiral dicarboxylic acid derivative of binaphthyl. This compound matters as a sophisticated organic building block, prized for its rigid, non-planar structure which is essential for creating chiral environments in advanced materials and catalysts. It is critically needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty materials industries for applications in asymmetric synthesis and the development of chiral ligands, polymers, and metal-organic frameworks (MOFs).

Application

• Chiral Ligand Synthesis: A key precursor for synthesizing BINOL and BINAP-type ligands used in asymmetric hydrogenation and other catalytic reactions.
• Pharmaceutical Intermediates: Serves as a critical building block in the development of enantiomerically pure active pharmaceutical ingredients (APIs).
• Advanced Material Development: Used in the construction of chiral metal-organic frameworks (MOFs) and porous coordination polymers for separation and sensing.
• Polymer Chemistry: Incorporated into chiral polymers and dendrimers to impart specific optical or catalytic properties.
• Agrochemical Research: Employed in the synthesis of chiral compounds for crop protection agents.
• Analytical Chiral Stationary Phases: Can be derivatized for use in high-performance liquid chromatography (HPLC) columns for enantiomer separation.
