General description

Biphenyl-4,4′-dicarboxylic acid (BPDC) belongs to the class of monomers known as aromatic dicarboxylic acids. It is used to prepare BPDC-based polymers, which exhibit excellent thermal stability, making them suitable for applications where high-temperature resistance is required. These polymers also demonstrate high electrical insulation properties due to their low dielectric constant and high breakdown strength. They find applications in the electrical and electronics industry for insulation, encapsulation, and fabrication of high-performance electronic devices.

Application

Biphenyl-4,4′-dicarboxylic acid can be used:
  • As a key component In the synthesis of nematic aromatic polyesters which are valuable in the development of liquid crystal polymers with potential applications in electronics, optical devices automotive, and textiles.
  • As a linker or ligand in the synthesis of metal-organic frameworks (MOFs) for a wide range of potential applications in areas such as gas storage, catalysis, sensing, and separation technology.
  • As a building block in biomedical applications for the synthesis of various pharmaceutical compounds and materials with biological activity. It can also be utilized in the development of drug delivery systems and biomaterials due to its chemical properties.
