Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting the central nervous system. Its structure allows for the formation of biologically active compounds, including those with potential anxiolytic, antidepressant, or anticonvulsant properties. The amine and carboxylic acid functional groups enable easy modification for building more complex molecules. It is also employed in the preparation of cyclic peptides and peptidomimetics, where its conformational rigidity enhances binding selectivity and metabolic stability. Additionally, it finds use in medicinal chemistry research for structure-activity relationship (SAR) studies due to its stereochemical diversity.
