Used as a key monomer in the synthesis of high-performance polymers, particularly in the production of specialty polyesters and polyamides. Its bulky tert-butyl group enhances thermal stability and improves solubility of the resulting polymers, making them suitable for advanced coating applications and engineering plastics. Also employed in the development of metal-organic frameworks (MOFs) due to its rigid structure and ability to coordinate with metal ions, enabling applications in gas storage and catalysis. Additionally, it serves as a building block in the design of functional materials requiring controlled porosity and chemical resistance.
