Used as a high-performance monomer in the synthesis of polyimides and epoxy resins, offering excellent thermal stability and mechanical strength. Its unique structure with hydroxyl and amino groups enables crosslinking in advanced polymer networks, making it suitable for aerospace, electronics, and composite materials. Also employed in the development of flame-retardant materials and high-temperature adhesives due to its robust aromatic framework. Shows promise in membrane applications for gas separation and fuel cells owing to its rigid, hydrophilic characteristics.
