AureChem provides high-purity 3,4'-Oxydianiline (3,4'-ODA, CAS 2657-87-6), a key diamine monomer featuring a flexible ether linkage and an asymmetric structure. This unique 3,4'-substitution pattern enhances solubility and reduces crystallinity, making it valuable for synthesizing high-performance polyimides with a balance of thermal stability, flexibility, and processability. These advanced polym
