Description

[1,1':4',1''-Terphenyl]-4,4''-Dicarboxylic Acid, 2',3',5',6'-Tetrafluoro- (9Ci) is a high-purity, fluorinated terphenyl derivative that serves as a critical advanced intermediate in organic synthesis. Its value lies in its rigid, conjugated aromatic structure and the electron-withdrawing properties imparted by the fluorine substituents, making it essential for constructing sophisticated molecular architectures. This compound is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly for developing novel active ingredients and organic electronic materials.

Application

• Pharmaceutical Intermediate: Serves as a key building block for the synthesis of novel active pharmaceutical ingredients (APIs), especially those requiring rigid, planar scaffolds for target binding.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and pesticides where the fluorinated terphenyl core can enhance biological activity and environmental stability.
• Organic Electronic Materials: Acts as a precursor for electron-transport materials, host materials, or ligands in OLEDs (Organic Light-Emitting Diodes) and OFETs (Organic Field-Effect Transistors).
• Ligand Synthesis for Catalysis: Utilized to create sophisticated, electron-deficient ligands for transition metal catalysis, enabling challenging cross-coupling and other synthetic transformations.
• Advanced Polymer Monomer: Functions as a monomer for producing high-performance, thermally stable, and chemically resistant polyamides, polyimides, or polyesters.
• Liquid Crystal & Display Technology: Investigated as a core component in the development of fluorinated liquid crystals for advanced display applications.
• Academic & Industrial R&D: Employed in research laboratories for fundamental studies in organic chemistry, materials science, and supramolecular chemistry.
