Product Description:

5-Aminoisophthalic acid is an aromatic dicarboxylic acid derivative featuring an amino group at the 5-position of the benzene ring. This bifunctional molecule contains both a carboxylic acid group and an amine group, making it a versatile building block. Its primary and most significant application is as a key monomer or linker in the synthesis of advanced porous materials, particularly Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs). The two carboxylate groups provide strong coordination sites for metal ions in MOF construction, while the amino group can be used for post-synthetic modification or to impart specific functionality to the framework. It is also employed in the synthesis of polyamides, polyimides, and other high-performance polymers, where it contributes to thermal stability and mechanical properties. As a commercially available compound, it serves as a useful organic synthesis intermediate in research laboratories for constructing more complex molecules containing isophthalic acid cores.
