Used as a chiral derivatizing agent in the analysis of amino acids and amines, particularly in gas chromatography and mass spectrometry. Its trifluoroacetyl group enhances volatility and provides strong electron-capturing properties, improving detection sensitivity. Commonly employed in stereochemical studies due to its ability to form diastereomeric derivatives, allowing separation and quantification of enantiomers. Also utilized in synthetic organic chemistry for protection and activation strategies in peptide synthesis.
