Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of beta-blockers and other cardiovascular drugs. Its stereochemistry allows for selective interactions in biological systems, making it valuable in asymmetric synthesis. Commonly employed in the preparation of ester prodrugs due to the carboxylic acid group, which can improve bioavailability. Also utilized in the manufacture of agrochemicals and specialty polymers where optical purity is critical.
