✦ Synopsis

Derivatization of alkylated hydroxyaromatics with N-methyl-bis(triflu0racetamide) is used for a rapid screening for alkylated hydroxyaromatic compounds in complex mixtures by tandem mass spectrometry. Applications are based on a detailed investigation of the fragmentation reactions of derivatized alkylated phenols, 2,s dihydroindenols, indenols, 1,2,3,Qtetrahydronaphthols and naphthols. As shown by daughter-ion mass spectra obtained in different field-free regions of a BEQQ-instrument, the loss of CF,COOH, CF,CO' or CF,COO', respectively, is common for the compounds studied and can be used for their detection by means of neutral mass loss scans.

This paper shows the first application of field desorption-tandem mass spectrometry (FD-MS/MS) in a hybrid sector, orthogonal acceleration time-of-flight mass spectrometer. This instrumentation has significant advantages in detection limits for MS/MS experiments over four sector mass spectrometers.
