Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the production of pharmaceuticals such as antiviral and anticancer agents. It participates in ring formation reactions to build nitrogen- and oxygen-containing structures, which are common in bioactive molecules. Also employed in the development of agrochemicals and functional materials due to its reactivity and ability to form stable derivatives. Its hydrochloride form enhances solubility and stability in aqueous reaction environments, making it suitable for use in various solution-phase syntheses.
