Description

[1,1':3',1''-Terphenyl]-3,3'',5,5''-Tetracarboxylic Acid, 5'-Methyl- is a high-purity, multifunctional organic building block characterized by its rigid terphenyl core and four strategically positioned carboxylic acid groups. This compound matters for its role as a critical precursor in the synthesis of advanced materials, particularly metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), where it acts as a polytopic linker. It is essential for researchers and manufacturers in the fields of porous materials, organic electronics, and specialty polymer chemistry who require precise molecular architectures for developing next-generation adsorbents, sensors, and catalysts.

Application

• Metal-Organic Framework (MOF) Synthesis: Serves as a key organic linker for constructing porous MOFs with tailored pore sizes and functionalities for gas storage, separation, and catalysis.
• Covalent Organic Framework (COF) Precursor: Used in the bottom-up synthesis of crystalline, porous organic polymers for applications in energy storage and photovoltaics.
• Functional Polymer Monomer: Acts as a monomer for creating high-performance polyimides, polyamides, and other polymers with enhanced thermal stability and mechanical properties.
• Ligand for Coordination Chemistry: Provides multiple binding sites for metal ions, useful in creating complex catalysts and luminescent materials.
• Pharmaceutical Intermediate: Employed in the research and development of complex drug molecules and active pharmaceutical ingredients (APIs).
• Organic Semiconductor Research: Investigated as a component in the development of novel organic electronic materials due to its conjugated structure.

Quality Control

Our [1,1':3',1''-Terphenyl]-3,3'',5,5''-Tetracarboxylic Acid, 5'-Methyl- is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and industrial applications. All materials are characterized by advanced analytical techniques including NMR and HPLC. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

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