Used as a chiral building block in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure incorporates a fluorenylmethyloxycarbonyl (Fmoc) protecting group, making it valuable in solid-phase peptide synthesis where selective deprotection and coupling are required. The presence of fluorine enhances binding affinity and metabolic stability in final drug candidates. Commonly employed in research settings for constructing complex molecules with stereoselective control.
