Used as a chiral derivatizing agent in the synthesis of pharmaceuticals, particularly in asymmetric synthesis and resolution of enantiomers. Its trifluoroacetyl group enhances reactivity and selectivity in coupling reactions, making it valuable in the preparation of peptide mimetics and beta-amino acids. Commonly employed in liquid chromatography and NMR spectroscopy for enantiomeric purity analysis due to the distinct signals provided by the fluorine atoms. Also utilized in agrochemical and fine chemical industries where stereochemical control is critical.
