Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for protease inhibitors due to its ability to mimic peptide bonds and interact with enzyme active sites. Commonly employed in the development of anticoagulant drugs, where it enhances selectivity and binding affinity toward serine proteases such as thrombin and trypsin. Also utilized in the synthesis of heterocyclic compounds for medicinal chemistry research.
