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 fluorinated analogs in drug candidates, improving metabolic stability and bioavailability. Commonly employed in the preparation of central nervous system agents and anti-inflammatory compounds. Also utilized in asymmetric synthesis due to the amine functionality, which can act as a directing group or catalyst precursor.
