Used as a key intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in the development of antifungal and antimicrobial agents. Its disulfide bridge and imidazole groups enable strong interactions with biological targets, making it valuable in medicinal chemistry. Also employed in coordination chemistry as a ligand for metal ions, facilitating catalytic processes and the formation of metal-organic frameworks. Shows potential in research related to enzyme inhibition due to its structural similarity to natural histidine-containing biomolecules.
