Used as a crosslinking agent in high-performance polymers, particularly in the development of heat-resistant and mechanically strong epoxy resins. It enables improved thermal stability and toughness in composite materials used in aerospace, electronics, and structural adhesives. Also employed in the synthesis of liquid crystalline polymers due to its rigid molecular structure, which supports ordered phase formation. Its cyano groups allow further chemical modification, making it valuable in specialty polymer design for advanced engineering applications.
