4,4'-Bis(4-aminophenoxy)biphenyl (BAPB), identified by CAS No. 13080-85-8, is a highly versatile diamine that serves as a crucial intermediate in various advanced material applications. Its unique molecular structure, combining the rigidity of a biphenyl core with the flexibility of ether linkages, endows it with desirable properties for high-performance polymers, electronic materials, and porous frameworks. For researchers and manufacturers, understanding these properties and identifying reliable sources is key.

The typical appearance of BAPB is a white powder, with a high purity generally specified at 97% or above. Its melting point usually falls between 197-200°C, indicating good thermal stability. These physical and chemical characteristics make it an excellent candidate for demanding synthetic processes. The amine functional groups present in BAPB are highly reactive, enabling its participation in polymerization reactions to create polyimides or condensation reactions to form Covalent Organic Frameworks (COFs).

Key applications for BAPB include its use as a monomer in the synthesis of high-performance polyimides, which are renowned for their exceptional thermal resistance and mechanical strength, finding use in aerospace and electrical insulation. Furthermore, BAPB is a significant intermediate in the production of materials for Organic Light-Emitting Diodes (OLEDs), contributing to the efficiency and stability of these display technologies. Researchers also utilize BAPB as a ligand in the synthesis of COFs, creating porous materials for advanced applications.

When seeking to buy BAPB, it is essential to partner with a reputable manufacturer or supplier. Companies often look for sources that can guarantee high purity and consistent quality, with many turning to specialized chemical suppliers in China. Accessing a detailed BAPB chemical datasheet from your prospective supplier is a crucial step to ensure the product meets your specific project requirements. By understanding the properties and applications of BAPB, you can make informed decisions for your material sourcing needs.
