Description

2",3'-Dinitro-[1,1':4',1":4",1"'-Quaterphenyl]-3,3'",5,5'"-Tetracarboxylic Acid is a high-purity, multifunctional aromatic compound characterized by its extended conjugated quaterphenyl backbone and multiple reactive carboxylic acid and nitro groups. This unique structure makes it a critical advanced intermediate for synthesizing complex organic electronic materials and specialty polymers. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel active ingredients and functional components.

Application

• Pharmaceutical Intermediate: Serves as a sophisticated building block for the synthesis of novel drug candidates, particularly in oncology and antiviral research, leveraging its polyfunctional nature for complex molecular architectures.
• Agrochemical Synthesis: Used in the development of new-generation herbicides and pesticides, where its aromatic nitro and acid groups contribute to unique biological activity and selectivity.
• Organic Electronic Materials: Acts as a precursor for organic semiconductors, light-emitting diodes (OLEDs), and photovoltaic materials due to its extended π-conjugated system and potential for further functionalization.
• Ligand and Catalyst Development: Employed in creating complex polydentate ligands for metal-organic frameworks (MOFs) and homogeneous catalysis, where its multiple coordination sites are advantageous.
• Polymer and Resin Chemistry: Functions as a cross-linking agent or monomer for producing high-performance, heat-resistant polymers, epoxy resins, and polyimides.
• Dye and Pigment Intermediate: Utilized in the synthesis of specialized azo dyes and high-stability pigments for industrial and optical applications.

Quality Control

Our 2",3'-Dinitro-[1,1':4',1":4",1"'-Quaterphenyl]-3,3'",5,5'"-Tetracarboxylic Acid is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the exacting standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical R&D and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the original container. Keep away from heat, sparks, and open flame.
