4,4”-Diamino-p-terphenyl（Cat No.:L027508）is an aromatic compound composed of three linearly connected benzene rings (terphenyl) with amino groups at the 4 and 4” positions. This rigid, rod-like molecule is widely used as a monomer in the synthesis of high-performance polymers, such as polyamides and polyimides, due to its thermal stability, mechanical strength, and extended π-conjugation. The diamino functionality enables facile condensation reactions with diacid derivatives, forming robust polymer backbones. It is also explored in organic electronics, liquid crystal materials, and advanced coatings, where structural rigidity and aromaticity are critical for performance.
