What is 3,4'-Oxydianiline?
Description
3,4'-Oxydianiline (3,4'-ODA) is a phenyl ether derivative capped at both ends with two amines in the para and meta positions. 3,4'-ODA is commonly used in the synthesis of polyimides which have multifunctional properties.3,4'-ODA is transparent and can be used as a substrate for displays. Polyimides are transparent and can be used as substrates for displays. 3,4'-ODA can also be used to synthesise organic porous materials with a BET surface area of up to 351 m2/g. Polyetherimide membranes made from this diamine structural unit show good permeation during water-isopropanol separation.
The Uses of 3,4'-Oxydianiline
3,4'-Oxydianiline is an ether organic substance and can be used as a pharmaceutical intermediate.
The Uses of 3,4'-Oxydianiline
3,4''-Diaminodiphenyl Ether, can be used for the synthesis of asymmetric soluble polyimides. It can also be used as a spacer in the preparation of glycine-based molecular tongs as inhibitors of β-amyloid peptide Aβ1-40 aggregation in vitro.
