Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of beta-blockers and other cardiovascular drugs. It serves as a key intermediate in the preparation of optically active compounds, enhancing the efficacy and specificity of the final drug products. Additionally, it is employed in asymmetric synthesis to create enantiomerically pure substances, which are crucial in developing drugs with reduced side effects and improved therapeutic outcomes. Its role in organic synthesis also extends to the creation of fine chemicals and agrochemicals, where chirality plays a significant role in biological activity.
