Analysis of insecticide synergists

The utility of a variety of chromatographic procedures (GLC, TLC, and GLC/MS) has been described for the determination of a variety of methylene dioxyphenyl insecticide synergists. Particular focus was placed on chromatographic aspects of the principal synergist, piperonyl butoxide, in relation to its trace impurities, determination in formulations, metabolism, residues, and stability.
