Used in pharmaceutical synthesis as a chiral building block for histidine-based compounds. Serves as an intermediate in the production of antiviral and antifungal agents. Also employed in the development of enzyme inhibitors due to its structural similarity to natural amino acids. Its imidazole ring enables coordination in catalytic systems, making it useful in asymmetric synthesis. Additionally, applied in research for designing peptidomimetics and bioactive molecules targeting neurological and metabolic disorders.
