Picolinyl esters as derivatives for the structural determination of long chain branched and unsaturated fatty acids
Abstract
3-Picolinyl esters were prepared from n-, iso-, anteiso- and unsaturated long chain fatty acids and were examined by gas chromatography and mass spectrometry. The spectra contained ions which were diagnostic of the position of both the methyl branching and the double bond, and could be rationalized by assuming hydrogen abstraction from the chain by the nitrogen of the pyridine ring and cleavage at the resulting radical site. The derivatives were easy to prepare and gave more informative spectra than the previously used pyrrolidides.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
