Used as a key intermediate in the synthesis of high-performance polyesters and polyamides, particularly in the production of liquid crystalline polymers (LCPs). These polymers exhibit excellent thermal stability, mechanical strength, and chemical resistance, making them suitable for electronic components, such as connectors and insulators, and in aerospace and automotive industries. Also employed in the development of advanced optical materials due to its ability to form highly ordered structures. Its bifunctional amine and ester groups enable cross-linking in specialty coatings and films with enhanced durability and barrier properties.
