Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the preparation of hydantoin-based drugs with antimicrobial or anticonvulsant properties. It serves as a building block in the development of bioactive molecules due to its ability to form cyclic ureides. Also employed in peptide chemistry and as a reagent in the synthesis of heterocyclic compounds. Its hydrochloride form enhances solubility and stability in aqueous reaction systems.
