Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. It serves as a building block in the production of certain antidepressants and antipsychotics due to its amine-functionalized aromatic structure. Also employed in the preparation of specialty polymers and dyes, where its reactivity allows for cross-linking and functional group modification. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction systems.
