AbstractDerivatization of alkylated hydroxyaromatics with N‐methyl‐bis(trifluoracetamide) 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‐terrahydronaphtbols and naphthols. As shown by daughter‐ion mass spectra obtained in different field‐free regions of a BEQQ‐instrument, the loss of CF3COOH, CF3CO˙ or CF3COO˙, respectively, is common for the compounds studied and can be used for their detection by means of neutral mass loss scans.
