Derivatization 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 CF 3 COOH, CF 3 CO˙ or CF 3 COO ˙ , respectively, is common for the compounds studied and can be used for their detection by means of neutral mass loss scans.
