Abstract
A relatively simp le and less expensive m ethod is p ropo sed fo r the
determ ination of cyhalofop2butyl (XDE2537) and its m etabo lites: R2(+ ) 222[ 42(22fluo ro242
cyanophenoxy) phenoxy ] p ropano ic acid (AC ID ); R2(+ ) 222[42 (42 carboxyl222fluo ro242
cyanophenoxy) phenoxy ] p ropano ic acid ( D IAC ID ); and 22[42(42carbamoyl222
fluo rophenoxy) phenoxy ] p ropano ic acid (AM IDE). Conversion of the parent compound to its
arylöalkylöo r halide derivative fo r determ ination by GC w as found unnecessary. O nly HPLC
w as used and under gradient elution all the four compounds separated w ell. Good recoveries
w ere obtained w ith the fo rtified so il and w ater samp les. Low pH w as impo rtant fo r the
extraction of the four components
