Triazolopyridine, a New Derivative for the Structural Determination of Fatty Acids by Gas Chromatography/Mass Spectrometry

Article abstract of DOI:10.1002/oms.1210230803

Triazolopyridine is proposed as a new derivative for the location of branches and double bonds in fatty acids.It is compared with previously used derivatives and found to be clearly superior to the pyrrolidide and slightly superior to the β-picolinyl ester with regard to the structure-specific fragmentation pattern.It is prepared by reacting the activated acid with 2-hydrazinopyridine followed by cyclization.
