Amitraz, N´-(2,4-dimethylphenyl)-N-[(2,4-dimethylphenyl)-
imino]methyl-N-methyl- methanimidamide, is an acaricide
used to control the infections produced by the mites on
cattle. Its use can cause the presence of residues in milk.
For this reason, the analysis of amitraz residues in milk has
received special attention in the scientific bibliography as
opposed to milk analysis. On the other hand, amitraz is a
very labile pesticide whose degradation products contain
the 2,4-dimethylaniline moiety[1-3]. Thus, the analysis of all
the residues containing this substructure is advisable. In this
context, the aim of this work has been to develop a method
to determine the amitraz total residues in milk.
