Used as a key intermediate in the synthesis of high-performance polymers and resins, particularly in the production of triazine-based epoxy hardeners. Enhances thermal stability and mechanical strength in coatings and composite materials. Employed in the development of advanced optical materials due to its rigid aromatic structure and electron-donating properties. Also applied in the fabrication of organic semiconductors and as a building block for covalent organic frameworks (COFs) in porous material design. Shows utility in corrosion-inhibiting coatings for metals owing to its strong adhesion and chemical resistance.
