Used as a specialty monomer in the synthesis of high-performance polymers, particularly polycarbonates and epoxy resins, due to its ability to enhance thermal stability and mechanical strength. Its unique structure with multiple aromatic rings and hydroxyl groups contributes to improved rigidity and resistance to heat degradation in polymer matrices. Also investigated for use in photoresists and optical materials because of its favorable transparency and refractive properties. Shows potential in developing advanced composite materials for aerospace and electronics where durability under high-temperature conditions is required.
