Product Details

3,4'-ODA CAS 2657-87-6 for Processable Polyimide Synthesis

3,4'-Oxydianiline, commonly known as 3,4'-ODA, is an ether-containing aromatic diamine monomer used as a structural building block in high-performance polyimide, polyamide and specialty polymer synthesis. Its asymmetric oxydianiline structure and flexible ether linkage make 3,4'-ODA relevant to polymer systems where solubility, processability, flexibility, thermal resistance and film-forming behavior need to be balanced.

3,4'-ODA belongs to the broader category of polyimide diamine monomers and is also part of Aure Chemical’s polyimide diamine monomers supply portfolio. Compared with more symmetrical oxydianiline structures, 3,4'-ODA may support processability and reduced crystallinity depending on the paired dianhydride, formulation and processing conditions.

Molecular Structure

Key Features in Polyimide Design

Ether-containing aromatic diamine structure, relevant to flexible and processable polyimide diamine monomers.
Asymmetric 3,4'-substitution pattern may help reduce crystallinity and improve solubility depending on the paired dianhydride and polymer architecture.
Flexible ether linkage may support chain mobility, processability and film-forming behavior in selected polyimide systems.
3,4'-ODA can be considered in flexible and processable polyimide systems where solubility, processing and material toughness are important.
Final material properties depend on monomer purity, dianhydride selection, solvent system, imidization conditions and polymer processing method.

Pairing 3,4'-ODA with Dianhydride Monomers

In polyimide synthesis, 3,4'-ODA may be evaluated with selected polyimide dianhydride monomers to design flexible, processable and specialty PI systems. Ether-containing dianhydrides such as ODPA CAS 1823-59-2 may further support processability and film-forming behavior.

Rigid aromatic dianhydrides such as BPDA CAS 2420-87-3 or BTDA CAS 2421-28-5 may be considered when thermal resistance and dimensional stability are important, while fluorinated dianhydrides such as 6FDA CAS 1107-00-2 may be evaluated when optical, dielectric or moisture-related properties are part of the target polymer design.

Application Context of 3,4'-ODA in Polyimide Systems

3,4'-ODA is typically used as a structural diamine monomer rather than a finished application material. It is commonly discussed in flexible, processable and specialty polyimide material development, where asymmetric aromatic structure and ether linkage can influence solubility, polymer morphology and processing behavior.

Flexible and processable polyimide systems – solubility, chain flexibility and film formation considerations.
Specialty functional polyimide materials – asymmetric diamine selection for advanced polymer research.
Electronics and semiconductor polyimide applications – insulation, film processing and electronic material requirements.
High-temperature polyimide applications – thermal resistance and high-performance polymer environments.
