Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its functional groups—amino and hydroxyl—allow for versatile reactivity, enabling the formation of amides, esters, and other derivatives. Commonly employed in the development of active pharmaceutical ingredients (APIs), especially in the synthesis of beta-blockers and other cardiovascular drugs. Also utilized in the preparation of chiral building blocks for asymmetric synthesis. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction systems.
