Description

1,1'-Bis(4-Carboxyphenyl)Methanol is a high-purity organic compound featuring a central methanol group flanked by two para-carboxyphenyl rings. This bifunctional structure, containing both carboxylic acid and benzylic alcohol groups, makes it a versatile and valuable building block for advanced chemical synthesis. It is primarily sought after by R&D and production teams in the pharmaceutical and specialty chemical industries for creating complex molecules, including ligands, polymers, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs), particularly those requiring rigid, functionalized biphenyl structures.
• Ligand Synthesis: Used to create sophisticated chelating ligands for catalysis and metal-organic frameworks (MOFs) due to its multiple coordination sites.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for producing high-performance polymers, polyesters, and epoxy resins with enhanced thermal and mechanical properties.
• Organic Synthesis Building Block: Employed in research and development for constructing complex organic architectures, including dendrimers and macrocycles.
• Material Science Research: Utilized in developing advanced materials such as organic semiconductors and nonlinear optical (NLO) materials.
• Fine Chemical Production: Acts as an intermediate in the manufacture of dyes, pigments, and other specialty fine chemicals.

Quality Control

Our 1,1'-Bis(4-Carboxyphenyl)Methanol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for research and synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
