Used in biochemical research, it serves as a precursor in the synthesis of various biologically active compounds, particularly those related to histidine metabolism. It is also employed in the study of enzyme mechanisms, especially those involving histidine residues in proteins. Additionally, it finds application in the development of pharmaceuticals targeting conditions like inflammation and neurodegenerative diseases due to its role in modulating histamine pathways. In industrial settings, it is utilized in the production of specialty chemicals and as an intermediate in organic synthesis. Its antioxidant properties make it relevant in formulations aimed at reducing oxidative stress in biological systems.
