Analytically useful pentafluoro ketone derivatives of fatty acids are described. The gas chromatographic/ mass spectrometric characteristics of these new derivatives are compared with those of methyl, trimethylsilyl and pentafluorobenzyl esters. Pentafluoro ketones exhibit excellent chromatographic
