Description

[1,1':3',1''-Terphenyl]-4,4'',5'-Tricarboxylic Acid, 2'-Amino- is a high-purity, multifunctional organic building block characterized by its rigid terphenyl core and strategically positioned amino and carboxylic acid functional groups. This compound matters for its role as a key precursor in the synthesis of advanced materials, where its molecular structure enables precise control over material properties. It is primarily needed by researchers and manufacturers in the fields of organic electronics, metal-organic frameworks (MOFs), and specialty polymers.

Application

• Organic Semiconductor Precursor: Serves as a critical building block for hole-transport materials (HTMs) and electron-transport materials in OLEDs and perovskite solar cells.
• Metal-Organic Framework (MOF) Synthesis: Used as a multitopic organic linker to construct novel MOFs with specific pore geometries for gas storage, separation, or catalysis.
• Functional Polymer Monomer: Enables the creation of polyamides, polyimides, or other high-performance polymers with enhanced thermal stability and mechanical properties.
• Pharmaceutical Intermediate: Acts as a sophisticated synthon in the research and development of complex active pharmaceutical ingredients (APIs).
• Dye and Pigment Chemistry: Utilized in the synthesis of novel organic dyes and pigments due to its conjugated system and functional handles.
• Ligand for Catalysis: Can be derivatized to form chelating ligands for transition metal catalysts used in cross-coupling and other organic transformations.

Quality Control

Our [1,1':3',1''-Terphenyl]-4,4'',5'-Tricarboxylic Acid, 2'-Amino- is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and elemental analysis, to ensure it meets the high standards required for research and advanced material synthesis. Certificates of Analysis (COA) with detailed chromatographic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect purity and performance. For long-term storage, consider using desiccants.
