Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and decongestants. Its enantiomerically pure structure makes it valuable in asymmetric synthesis, where stereochemistry plays a critical role in drug activity. Commonly employed in the preparation of bioactive molecules requiring specific stereochemical configuration for optimal receptor binding. Also utilized in research settings for the resolution of racemic mixtures and as a reagent in stereoselective transformations.
