Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its fluorinated aromatic structure makes it valuable in medicinal chemistry for modulating metabolic stability, lipophilicity, and binding affinity. Commonly employed in asymmetric synthesis and catalysis research, it serves as an intermediate in the preparation of more complex fluorinated organic molecules with potential therapeutic effects.
