For researchers and procurement specialists in the advanced materials sector, sourcing high-purity chemical intermediates is paramount to achieving project success. One such critical compound is 1,4-Bis(4-aminophenoxy)benzene, identified by CAS number 3491-12-1. This diamine monomer is a cornerstone in the synthesis of advanced polymers like polyimides and is crucial for applications ranging from high-performance membranes to cutting-edge OLED technology. If you are looking to buy this essential chemical, understanding its properties and where to find reliable suppliers is key.

1,4-Bis(4-aminophenoxy)benzene (TPE-Q) is a white powder with a high melting point, indicative of its robust molecular structure. Its chemical formula, C18H16N2O2, and molecular weight of approximately 292.33 g/mol, define its role as a versatile building block. The presence of two amine groups allows it to readily react with compounds like dianhydrides to form long, stable polymer chains. This makes it an ideal monomer for producing materials that can withstand extreme temperatures and harsh operational conditions. As a result, it finds extensive use in industries that demand uncompromising material integrity.

The application landscape for CAS 3491-12-1 is broad. In the field of polymer science, it is a key component for manufacturing polyimides used in nanofiltration membranes. These membranes are vital for industrial separation processes, contributing to efficiency and sustainability. Furthermore, the thermal stability offered by polyimides derived from TPE-Q makes them suitable for flexible substrates in electronic applications, including advanced displays and sensors. When you need to purchase these specialized polymers, sourcing the correct monomer is the first step.

Another significant application lies in the development of Covalent Organic Frameworks (COFs). COFs are highly ordered porous materials with immense potential in areas such as gas adsorption, catalysis, and drug delivery. 1,4-Bis(4-aminophenoxy)benzene serves as a vital diamine ligand in constructing these intricate framework structures. Its availability from a trusted manufacturer ensures that the synthesis of novel COFs can proceed without interruption.

The electronics industry also relies heavily on intermediates like TPE-Q. It is used in the synthesis of materials for OLEDs, where precise molecular design is critical for device performance, efficiency, and longevity. The electron-donating phenoxy groups contribute to the desired electronic properties, making it a valuable component for optoelectronic applications. For companies seeking to innovate in this rapidly evolving field, securing a consistent supply of high-quality materials is essential. Understanding the price fluctuations and lead times from various suppliers is part of a successful procurement strategy.
