The intricate world of organic chemistry provides the building blocks for countless advanced materials, and [p-Terphenyl]-4,4''-dicarboxylic acid (CAS: 13653-84-4) is a prime example. Understanding its chemical structure and synthesis is fundamental for researchers and manufacturers looking to leverage its unique properties. This compound is highly valued as a chemical intermediate, particularly for its role in creating Metal-Organic Frameworks (MOFs) and other functional materials.

Chemically, [p-Terphenyl]-4,4''-dicarboxylic acid is characterized by a three-ring system, specifically a terphenyl backbone. This backbone consists of three phenyl rings linked together in a linear fashion. The key functional groups are two carboxylic acid (-COOH) moieties, attached at the para positions of the two outer phenyl rings. This linear, rigid structure, combined with the terminal reactive carboxylic acid groups, makes it an excellent rigid linker or monomer for various chemical syntheses. Its molecular formula is C20H14O4, with a molecular weight of approximately 318.32 g/mol.

The synthesis of [p-Terphenyl]-4,4''-dicarboxylic acid typically involves palladium-catalyzed cross-coupling reactions, such as Suzuki coupling or Yamamoto coupling. For instance, a common route might involve the coupling of a dihalobenzene derivative with a phenylboronic acid derivative that already contains the carboxylic acid groups, or vice versa, followed by oxidation or hydrolysis to yield the dicarboxylic acid. The precision required in these reactions ensures the high purity (often specified as 98% min) that is essential for its downstream applications. Companies that buy this chemical intermediate rely on manufacturers who have mastered these synthetic pathways.

As a vital chemical intermediate, the demand for [p-Terphenyl]-4,4''-dicarboxylic acid is driven by its utility in advanced material science. Its rigidity and defined geometry are instrumental in forming stable, porous structures in MOFs, which are crucial for applications like gas adsorption and catalysis. Researchers also utilize it in the synthesis of advanced polymers, contributing to materials with superior thermal and mechanical properties. When seeking to purchase this compound, identifying a reputable manufacturer that guarantees high purity and consistency is paramount.

For those in the industry, understanding the synthesis and properties allows for more informed procurement decisions. Sourcing from a reliable supplier in China can provide access to this material at competitive price points, while maintaining the quality required for sensitive applications. Exploring the product offerings from established manufacturers, perhaps by requesting a free sample, is a prudent step before committing to larger orders.

In summary, [p-Terphenyl]-4,4''-dicarboxylic acid (CAS: 13653-84-4) is a compound with a well-defined chemical structure and synthesis pathways that underscore its importance as a versatile chemical intermediate. Its rigid, linear terphenyl backbone and terminal carboxylic acid groups make it indispensable for creating advanced materials, and securing a high-purity supply from trusted manufacturers is key to unlocking its full potential.
