Used as a key monomer in the synthesis of high-performance polymers, particularly in the production of functional polyesters and polyamides. Its unique structure with multiple reactive sites allows for cross-linking, enhancing thermal stability and mechanical strength of the resulting materials. Commonly applied in specialty coatings, flame-retardant textiles, and engineering plastics. Also explored in metal-organic frameworks (MOFs) due to its ability to chelate metal ions, making it useful in gas storage and catalysis applications.
