Used primarily as a reactive intermediate in organic synthesis, this compound serves in the preparation of chelating agents and polymers. Its anhydride groups readily react with amines and alcohols, making it valuable for modifying biomolecules and creating specialty resins. It is also employed in the development of crosslinking agents for coatings and adhesives, where it enhances thermal and chemical resistance. Due to its ability to form stable complexes with metal ions, it finds use in catalysis and in the synthesis of metal-organic frameworks.
