Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of beta-blockers and other bioactive molecules. Its stereochemistry allows for selective reactions in asymmetric synthesis, making it valuable in creating enantiomerically pure compounds. Commonly employed in organic chemistry research for constructing complex molecules where control over three-dimensional structure is critical. Also utilized in the preparation of enzyme inhibitors and antimicrobial agents due to its reactive bromo and hydroxy functional groups.
