Cas no 74-31-7 (N1,N4-Diphenylbenzene-1,4-diamine)
N1,N4-Diphenylbenzene-1,4-diamine is an aromatic diamine compound characterized by its two phenyl groups attached to the nitrogen atoms of a central benzene-1,4-diamine core. This structure imparts stability and electron-rich properties, making it useful in applications such as organic synthesis, polymer chemistry, and materials science. Its rigid aromatic framework contributes to high thermal stability, while the amine groups enable reactivity in condensation and crosslinking reactions. The compound is often employed as a building block for advanced materials, including polyimides and conductive polymers, due to its ability to enhance mechanical and electronic properties. Proper handling is advised due to potential sensitivity to oxidation.
