Derivatization of alkylated hydroxyaromatics with N-methyl-bis(trifluoroacetamide) 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, 2,3-dihydroindenols, indenols, 1,2,3,4-tetrahydronaphthols and naphthols.As shown by daughter-ion mass spectra obtained in different field-free regions ofba BEQQ-instrument, the loss of CF3COOH, CF3CO radical or CF3COO radical, respectively, is common for the compounds studied and acn be used for their detection by means of neutral mass loss scans.
