Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its fluorinated structure enhances metabolic stability and blood-brain barrier penetration, making it valuable in the design of antidepressants, antipsychotics, and other neuroactive drugs. The compound's stereochemistry is critical for biological activity, allowing for selective interaction with neuronal receptors and enzymes. It is also employed in the preparation of fluorinated analogs in medicinal chemistry research to improve drug potency and pharmacokinetic profiles.
