Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain anticoagulant drugs and heterocyclic compounds. It serves as a building block in organic synthesis due to the presence of both amino and hydroxyl functional groups, enabling the formation of Schiff bases and other derivatives. Commonly employed in research settings for developing bioactive molecules and in the preparation of dyes and fluorescent probes. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction systems.
