3,4'-Oxydianiline (3,4'-ODA) CAS 2657-87-6

An asymmetrical diamine building block

As intermediate for the preparation of polyimides in application of transparent substrates, organic porous materials, and pervaporation membranes

Overview
Related Products

3,4'-Oxydianiline (3,4'-ODA), CAS number 2657-87-6, is a phenyl ether derivative capped with two amines at para- and meta-position on either end. 3,4'-Oxydianiline is typically used for synthesizing polyimides with multi-functionalities. Due to the meta-substituted amine hindering the intermolecular packing, the polyimides are transparent. Therefore, they are applied as substrates in displays. The high thermal stability (210 °C) allows these polyimides to be used as substrates for sintering integrated devices.

3,4'-ODA is also used in synthesizing organic porous materials with BET surface area up to 351 m²/g. The polyetherimide membranes obtained from this diamine building block show effectiveness on pervaporation for water-isopropanol separation.
