Used primarily as a key intermediate in organic synthesis, particularly in the development of pharmaceuticals. Its cyclic imide structure makes it valuable for constructing complex nitrogen-containing molecules, including bioactive compounds and drug candidates. It is often employed in the synthesis of peptidomimetics and heterocyclic derivatives due to its ability to mimic peptide bonds and participate in ring-forming reactions. Additionally, it serves as a building block in the preparation of natural product analogs and medicinal chemistry research.
