Used primarily as a pharmaceutical intermediate in the synthesis of beta-adrenergic blocking agents, particularly in the production of beta-blockers like metoprolol. It serves as a key chiral building block due to its structural similarity to the core framework of many cardioselective drugs. Its hydroxyl and amine functional groups allow for easy modification and coupling in multi-step organic syntheses. Also employed in the development of fine chemicals and active pharmaceutical ingredients (APIs) requiring amino alcohol motifs. Its solubility in both aqueous and organic media enhances its utility in various reaction conditions.
