Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enantiomerically pure drugs. Its stereochemistry allows for selective interactions in biological systems, making it valuable in asymmetric synthesis. Commonly employed in the preparation of beta-blockers and other cardiovascular agents. Also utilized in the resolution of racemic mixtures due to its optical activity. Serves as an intermediate in the production of agrochemicals and fine chemicals where chirality plays a critical role in activity.
