Used in the synthesis of pharmaceutical intermediates, particularly in the production of analgesic and anti-inflammatory drugs. It serves as a building block for complex organic molecules due to the presence of both amino and hydroxyl functional groups, which allow for diverse chemical modifications. Commonly employed in research settings for developing active pharmaceutical ingredients (APIs) and in the preparation of beta-adrenergic receptor agonists. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction systems.
