Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the formation of bioactive molecules through functional group transformations. Commonly employed in medicinal chemistry for constructing benzotriazole-based compounds that exhibit enzyme inhibitory activity. Also utilized in agrochemicals for designing new active ingredients with improved stability and efficacy. Serves as a building block in click chemistry and heterocyclic compound synthesis due to its reactive ester and aromatic nitrogen-rich core.
