Product Description:
1,4 - Benzenedicarboxylic acid bis(4 - aminophenyl) ester typically exists as a solid, often appearing as white crystals. Its molecular formula is C??H??N?O?, with a molecular weight of 348.35. It has a melting point of around 238 °C, a predicted boiling point of 608.6 ± 50.0 °C, and a density of approximately 1.335. The pKa value is predicted to be 4.07 ± 0.10. This compound has limited solubility in water but better solubility in some polar organic solvents. It serves as an important intermediate in organic synthesis, especially in the preparation of materials like polyimides. Store it in a cool, dry place away from moisture and strong oxidizing agents.

Application: 

1,4 - Benzenedicarboxylic acid bis(4 - aminophenyl) ester is chiefly applied in synthesizing high - performance polyimides. It strengthens the polyimide's thermal stability, mechanical strength, and chemical resistance. Also, it serves as a crucial intermediate in the production of certain pharmaceutical compounds and is used in developing functional materials for electronics, like enhancing the properties of insulating materials for circuit boards.
