Assays for typical pyrethroidal insecticides were developed to determine their absolute purity. Resmethrin, furamethrin and phenothrin could be determined by a neutralizing titration after hydrolyzing with potassium hydroxide to achieve relative standard deviations (RSD) of 0.10, 0.19 and 0.35%, respectively. Allethrin, phthalthrin and furamethrin could be determined by a neutralizing titration in a non-aqueous solvent after reacting with ethylenediamine to achieve RSD values of 0.10, 0.14 and 0.09%, and permethrin by a chlorine determination with the oxygen combustion method to achieve RSD of 0.23%. These methods are effective for assays of the reference standards because there is no necessity for another reference standard.
