Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of beta-blockers and other cardiovascular drugs. Its functional groups—bromine, hydroxyl, and nitrile—allow for selective chemical modifications, enabling the construction of complex organic molecules. Commonly employed in research settings for creating analogs in structure-activity relationship (SAR) studies. Also utilized in the preparation of chiral building blocks through asymmetric synthesis, supporting the production of enantiomerically pure drugs.
