Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enantiomerically pure drugs. It plays a key role in creating compounds with specific biological activities, such as receptor agonists or antagonists. Additionally, it is employed in asymmetric catalysis to produce optically active intermediates for agrochemicals and fine chemicals. Its tert-butyl group enhances steric hindrance, making it valuable in designing molecules with improved selectivity and stability.
