Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of analgesic and anti-inflammatory agents. It serves as a building block for active pharmaceutical ingredients (APIs) due to the presence of both amine and phenolic functional groups, which allow for diverse chemical modifications. Commonly employed in the preparation of local anesthetics and centrally acting muscle relaxants. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction systems and purification processes during drug manufacturing. Also utilized in research settings for the development of novel organic compounds with biological activity.
