HPLC Separation of Triclopyr

Triclopyr (3,5,6-Trichloro-2-pyridinyloxyacetic acid) is sold under the brand names Turflon, Weed-B-Gon, and Brush-B-Gon. Triclopyr controls broad leaf plants and is very similar to the pesticide it replaced 2,4,5-T. The EURL (European Union Reference Laboratory) included triclopyr in an analysis of acidic pesticides using QuEChERS method. Primesep 100 and Obelisc R were used to retain and separate triclopyr from impurities. Method is LC/MS compatible and developed to be used for many pesticides.
