Bis(p-aminophenyl) ether (Cat No.: R017963), also known as 4,4′-diaminodiphenyl ether or oxybenidine, is an aromatic diamine consisting of two para-substituted aniline rings linked by an ether (–O–) bridge. It is a key monomer in the production of high-performance polyamides and polyimides, such as polyetherimide (PEI), known for their exceptional thermal and mechanical properties. Its rigid, planar structure and reactive amine groups make it suitable for advanced materials used in aerospace, electronics, and engineering applications where chemical resistance and durability are essential.
