Product Name: 4,4'-Biphenyldicarboxylic Acid – High Purity Organic Acid for Polymer and Specialty Applications
CAS Number: 787-70-2
4,4'-Biphenyldicarboxylic Acid is a high-purity aromatic dicarboxylic acid widely used as an intermediate in the production of high-performance polymers, liquid crystal polymers, and specialty chemicals. It appears as a white crystalline powder, virtually odorless, and is sparingly soluble in water but highly soluble in organic solvents such as dimethylformamide, dimethyl sulfoxide, and N-methyl-2-pyrrolidone. Its chemical structure, featuring two carboxyl groups attached to a biphenyl core, provides excellent rigidity and thermal stability, which makes it a key building block in the synthesis of polyesters, polyimides, and other advanced materials requiring high mechanical strength and thermal resistance.
In polymer manufacturing, 4,4'-Biphenyldicarboxylic Acid is commonly used to produce polyethylene terephthalate (PET), liquid crystal polymers, and other high-performance polyesters that are applied in films, fibers, coatings, and engineering plastics. Its rigid biphenyl structure imparts superior dimensional stability, chemical resistance, and mechanical performance to the resulting polymers. This makes it highly suitable for electronic materials, high-temperature-resistant plastics, and precision components in the automotive, aerospace, and electronics industries.
Beyond polymer synthesis, 4,4'-Biphenyldicarboxylic Acid also serves as an important intermediate in the production of specialty chemicals, dyes, pharmaceuticals, and fine chemicals. Its high purity ensures minimal interference with subsequent chemical reactions, allowing formulators and chemists to design advanced products with predictable and reliable properties. Due to its low moisture content and thermal stability, it is easy to handle, store, and transport, maintaining consistent quality across long supply chains.
The product is produced under strict quality control conditions to ensure compliance with industrial and pharmaceutical-grade standards. Each batch is tested for purity, crystallinity, moisture content, and other critical parameters to ensure consistent performance in demanding applications. Proper handling involves storing the chemical in a cool, dry place, protected from strong oxidizers and moisture, to maintain its stability and effectiveness.
