Used as a reactive intermediate in the synthesis of advanced polymer materials, particularly in high-performance thermosetting resins. Its structure enables cross-linking with aromatic amines or anhydrides, enhancing thermal stability and mechanical strength in composite applications. Commonly applied in aerospace and electronics industries for manufacturing heat-resistant coatings, adhesives, and encapsulants. Also explored as a building block in specialty polyesters and polycarbonates where rigidity and oxidative resistance are required. Shows potential in photo-curable systems due to ester functionality and aromatic content, suitable for UV-resin formulations.
