Potential misidentification of trichlorophenylethanol in imported peppers.
During regulatory analyses for the determination of pesticide residues on agricultural commodities, a frequently encountered trichlorinated compound was misidentified by the NBS library search routine. This case history illustrates the need for more rigorous confirmation criteria when dealing with multi-chlorinated compounds where fragmentation can be dominated by methyl loss followed by loss of CO and HCI.
