Description

3,3'-Bis-Formylbiphenyl-2,2'-Diol (CAS NO 99124-34-2) is a high-purity, bifunctional organic building block featuring both formyl and phenolic hydroxyl groups on a biphenyl scaffold. This unique molecular architecture makes it a critical precursor for synthesizing complex macrocyclic ligands, advanced polymers, and specialty fine chemicals. It is primarily sought after by research institutions and industrial manufacturers in the fields of pharmaceutical intermediates, material science, and asymmetric catalysis.

Application

• Pharmaceutical Intermediate: Key precursor for the synthesis of novel drug candidates, particularly in developing enzyme inhibitors and receptor ligands.
• Macrocyclic Ligand Synthesis: Essential building block for creating sophisticated chelating agents and crown ether analogs used in metal ion separation and catalysis.
• Advanced Polymer Chemistry: Monomer for producing high-performance resins, liquid crystalline polymers, and specialty polyesters with tailored thermal and mechanical properties.
• Asymmetric Catalyst Development: Used to construct chiral ligands and organocatalysts for enantioselective synthesis in fine chemical production.
• Material Science Research: Employed in the development of organic electronic materials, molecular sensors, and non-linear optical (NLO) materials.
• Cross-Coupling Reactions: Serves as a versatile substrate in Suzuki, Heck, and other palladium-catalyzed cross-coupling reactions to build complex biaryl systems.
