Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of enzyme inhibitors and bioactive molecules. Its diazo group enables participation in cycloaddition and insertion reactions, making it valuable in constructing complex heterocyclic systems. Commonly employed in medicinal chemistry for scaffold diversification and in the preparation of peptidomimetics. Also utilized in catalysis studies involving transition metals, where the diazo functionality acts as a carbene precursor for C–H functionalization reactions.
