Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of beta-blockers and other cardiovascular drugs. Its epoxide ring allows for selective ring-opening reactions, enabling the introduction of functional groups in a stereocontrolled manner. Commonly employed in the preparation of optically active intermediates for drugs like propranolol and atenolol. Also utilized in the synthesis of fine chemicals, agrochemicals, and specialty polymers where enantiomeric purity is critical. Due to its reactivity, it serves as a precursor in asymmetric synthesis and is valued in research and development of new bioactive molecules.
