Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the creation of biologically active molecules, especially in central nervous system agents and anti-inflammatory compounds. Commonly employed in asymmetric synthesis due to its stereochemical stability and reactivity in coupling reactions. Also utilized in the preparation of intermediates for agrochemicals and specialty chemicals where fluorinated and chlorinated aryl groups enhance metabolic stability and binding affinity.
