The dienophile 4-methyl-1,2,4-triazoline-3,5-dione forms stable adducts with conjugated dienes by generating Diels-Alder cycloaddition products. The reaction is rapid, highly selective for conjugated dienes and the derivatives are suitable for analysis by gas chromatography. Their mass spectra are marked by their

[reaction: see text] The scope and generality of a new reaction of indoles with MTAD is discussed. In most cases the ene-type reaction proceeds within seconds or minutes at 0 degrees C to provide the urazole adducts in high yield.

The dienophile 4-methyl-1,2,4-triazoline-3,5-dione (MTAD) adducts of conjugated diene compounds were used to locate the position of the conjugated double bonds in the parent compounds by high-resolution gas chromatography and electron impact mass spectrometry. Their mass spectra are marked by recognizable

A mass spectrometric method for the detection of vitamin D3 metabolites is described. This method involves the derivatization of the metabolites by cycloaddition with 4-phenyl-1,2,4-triazoline-3,5-dione, followed by their characterization by continuous-flow fast atom bombardment (CF-FAB) tandem mass spectrometry (MS-MS) and
