The fast (30 s) and practical derivatization of three chlorinated phenols: 2,4,6-trichlorophenol, triclosan and pentachlorophenol for their subsequent detection by EI-GC-MS is presented. The protocol involves the use of the eco-friendly difluoromethylating agent diethyl (bromodifluoromethyl) phosphonate (DBDFP) and results in the efficient labeling of the phenols with the difluoromethyl (CF<sub>2</sub>H) group. In addition, the protocol works at room temperature thus eliminating the need of heating as in more conventional methods (e.g. silylation with BSTFA).
