Used as a diamine monomer in the synthesis of high-performance polyimides and polyamides, offering excellent thermal stability and mechanical strength. Commonly applied in aerospace, electronics, and semiconductor industries for insulation films, coatings, and encapsulants due to its ability to form rigid, heat-resistant polymers. Also utilized in liquid crystal displays (LCDs) as a building block for alignment layers, contributing to improved display durability and performance. Shows promise in advanced composite materials where resistance to harsh environments is required.
