Primarily used as a synthetic intermediate in advanced organic synthesis, especially in polymer chemistry and functional material development. The multiple 2,5-dioxofuran (maleic anhydride-like) moieties make it suitable for crosslinking reactions, copolymer formation, and surface modification of polymers. It may also be used in research involving reactive anhydride chemistry, drug delivery systems, or biofunctional materials due to its multiple reactive sites.
