Used as a monomer in the production of high-performance polycarbonates and epoxy resins due to its methyl-substituted bisphenol structure. Offers improved thermal stability and oxidative resistance compared to standard bisphenol-based polymers. Commonly applied in coatings, adhesives, and engineering plastics where enhanced durability is required. Also utilized in specialty polymers for electronic encapsulation and aerospace components owing to its rigid molecular framework and resistance to environmental degradation.
