Uses
3,3'-Diaminobenzophenone serves as a precursor for synthesizing bis(carboxyphthalimide)s via condensation with trimellitic anhydride[1]. It is used to produce thermoplastic and aromatic polyimides, including Lark-TPI and BTDA/DAB structures, by reacting with 3,3',4,4'-benzophenonetetracarboxylic dianhydride[2][3].
