Used in pharmaceutical synthesis, particularly as a chiral building block for active pharmaceutical ingredients (APIs). Its fluorinated structure enhances metabolic stability and bioavailability in drug candidates. Commonly applied in the development of central nervous system agents, antiviral drugs, and enzyme inhibitors. The stereochemistry and fluorine substitution make it valuable for optimizing drug potency and selectivity. Also employed in medicinal chemistry research for structure-activity relationship (SAR) studies.
