Used primarily as a reactive intermediate in organic synthesis, this compound is especially valuable in the preparation of functionalized polymers and specialty coatings. Its anhydride groups readily react with amines and alcohols, making it suitable for modifying resins and improving adhesion properties in coating formulations. It is also employed in the development of crosslinking agents for high-performance materials, including electronic encapsulants and composites. Additionally, it finds use in pharmaceutical research as a building block for synthesizing bioactive molecules due to its ability to form stable amide or ester linkages under mild conditions.
