In the metabolism of diclofop-methyl by tolerant plant species, three ring-hydroxylated metabolites were formed as major metabolites. For conclusive identification of these metabolites, authentic standards were required. Therefore, the following five isomers of hydroxylated diclofop-methyl were synthesized as possible standards for identification of the diclofop-methyl metabolites: methyl 2-[4-(2,4-dichloro-5-hydroxyphenoxy)phenoxy]propanoate, methyl 2-[4-(2,4-dichloro-3-hydroxyphenoxy)phenoxy]propanoate, methyl 2-[4-(2,4-dichloro-6-hydroxyphenoxy)phenoxy]propanoate, methyl 2-[4-(2,5-dichloro-4-hydroxyphenoxy)phenoxy]propanoate, and methyl 2-[4-(2,3-dichloro-4-hydroxy-phenoxy)phenoxy]propanoate.
