Used primarily as a reactive intermediate in the synthesis of high-performance polymers and resins. It is especially valuable in the production of epoxy resins due to its ability to form cross-linked networks with excellent thermal stability, mechanical strength, and electrical insulation properties. Commonly employed in composite materials for aerospace, electronics, and electrical encapsulation. Also utilized in coatings and adhesives requiring high durability and resistance to heat and chemicals. Its rigid cyclic structure contributes to improved glass transition temperatures in cured systems, making it suitable for advanced engineering applications.
