Gas chromatography-mass spectrometry of some biologically important short chain acid butyl esters.

Mass spectra of n-butyl esters of selected biologically important short chain fatty acids were obtained by using the technique of gas-liquid chromatography-mass spectrometry. The results indicate that simple cleavage is responsible for the primary fragmentation of the molecules. The mass spectral data are considered to be advantageous for the identification of unknown short chain acids.
