Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its primary amine and hydroxyl functional groups allow for versatile reactivity, enabling use in asymmetric synthesis and the development of enantiomerically pure drugs. Commonly employed in the preparation of beta-adrenergic receptor blockers and other cardiovascular medications. Also utilized in the design of enzyme inhibitors and as an intermediate in the manufacture of agrochemicals and specialty polymers.
