5-Nitroisophthalic acid (5-NIPA)

5-Nitroisophthalic Acid (5-NIPA) is a highly functionalized aromatic dicarboxylic acid featuring a nitro group at the 5-position of the benzene ring. This compound is widely used as a versatile intermediate in the synthesis of specialty polymers, metal-organic frameworks (MOFs), and advanced coatings. Its dual carboxylic acid groups enable strong chelation and crosslinking capabilities, while the nitro substituent enhances electron-withdrawing properties, making it ideal for high-performance resin formulations and electronic materials. 5-NIPA is also employed in the development of corrosion-resistant additives, pharmaceutical intermediates, and dye precursors. It offers excellent solubility in polar solvents and is compatible with various esterification and amidation reactions. Available in high-purity grades, it meets stringent quality standards for industrial and research applications. Its structural rigidity and reactive profile make it a preferred building block in functional materials, adhesives, and surface modification technologies.
