Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of central nervous system agents and antipsychotic drugs. Its structure supports enhanced metabolic stability and improved blood-brain barrier penetration, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in the preparation of chiral building blocks for asymmetric synthesis, where the amine group serves as a handle for further functionalization. Commonly applied in research settings for structure-activity relationship (SAR) studies involving phenylalkylamine derivatives.
