Abstract
The utility of cyclic boronate derivatives for the combined gas chromatography-mass spectrometry of 1,2- and 1,3- diols has been further extended by the application of chemical ionisation techniques. Abundant quasi-molecular ions (M+1) in the isobutane chemical ionisation spectra of the examples studied (which include the methaneboronates of monoglycerides, monoalkyl glyceryl ethers, a steroid, dihydrosphingosine and a ceramide) are frequently accompanied by intense and informative fragment ions.Keywords
