[p-Terphenyl]-4,4''-dicarboxylic acid, identified by CAS number 13653-84-4, is a chemical compound that stands out for its structural rigidity and bifunctional nature. As a chemical intermediate, its unique properties make it highly desirable for researchers and product formulators engaged in cutting-edge material science. Understanding these properties is key for anyone looking to buy this compound for advanced applications, such as the synthesis of Metal-Organic Frameworks (MOFs) or high-performance polymers.

The molecular structure of [p-Terphenyl]-4,4''-dicarboxylic acid features a linear terphenyl backbone, with carboxylic acid (-COOH) groups precisely positioned at the para (4 and 4'') positions of the terminal phenyl rings. This arrangement results in a molecule with a defined length and orientation, classifying it as a rigid linear linker. This geometric characteristic is fundamental to its utility in creating highly ordered supramolecular structures. The terphenyl core provides thermal stability and mechanical robustness to the materials it helps form.

A significant attribute of this compound is its bifunctionality, stemming from the presence of two carboxylic acid groups. These groups are reactive sites that readily participate in condensation reactions, esterification, and crucially, coordination with metal ions. In the context of MOF synthesis, these carboxylate groups act as anchor points, connecting metal clusters or ions to form the extended crystalline networks that define MOFs. The precise spatial arrangement of these groups on the terphenyl scaffold dictates the dimensionality and connectivity of the resultant framework, influencing pore size and surface area.

The typical appearance of [p-Terphenyl]-4,4''-dicarboxylic acid is as a white powder or crystalline solid, often with a purity of 98% or higher. This level of purity is vital for researchers and manufacturers who depend on predictable chemical behavior. As a prominent chemical intermediate, its availability from reliable sources, such as specialist manufacturers in China, ensures that scientists can procure this material with confidence. Exploring options to purchase it often involves comparing offerings from various suppliers based on purity, packaging, and overall value.

Beyond MOFs, the compound's properties lend themselves to other applications. It can be incorporated into polymers to enhance their thermal resistance and mechanical strength. Its planar structure and potential for pi-pi stacking interactions also suggest applications in organic electronics and supramolecular chemistry. For those looking to innovate in these fields, understanding the technical specifications and availability from a trusted supplier is the first step.

In conclusion, the inherent structural rigidity, bifunctionality, and high purity of [p-Terphenyl]-4,4''-dicarboxylic acid (CAS: 13653-84-4) make it an invaluable asset for material scientists. Whether you are designing next-generation porous materials or developing advanced polymers, securing this key organic building block from a reputable manufacturer is essential for driving innovation forward.
