Used in the synthesis of biologically active compounds, particularly as an intermediate in the development of pharmaceuticals targeting neurological and metabolic disorders. Its chiral structure makes it valuable in creating enantioselective drugs, where the (S)-configuration plays a critical role in biological activity. Commonly employed in peptide mimetics and enzyme inhibitor design, especially for proteases involved in disease pathways. Also utilized in research settings for labeling and probing protein interactions due to its amide and amino functional groups.
