L-Tryptophan is condensed with formaldehyde to yield 2,3,4,5-tetra-hydro-β-carboline-4-carboxylic acid. The trimethylsilyl derivative of this compound is suitable for selective ion monitoring during combined gas chromatography - mass spectrometry since it affords a relatively abundant molecular ion of high MSS.
