Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds. It serves in the development of pharmaceuticals due to its reactive functional groups that facilitate the formation of nitrogen-containing rings. Also employed in the synthesis of agrochemicals and bioactive molecules where amidine derivatives are required. Its hydrochloride form enhances solubility and stability in aqueous reaction conditions, making it suitable for use in peptide mimetics and enzyme inhibitor design.
