Thinlayer chromatographic separation and spectrophotometric determination of Phthalthrin

Abstract

A simple method for the determination of the new insecticide, N-(3, 4, 5, 6-tetrahydrophthalimido)-methyl-dl-cis-trans-chrysanthemate (Phthalthrin), in technical products, and in some formulations has been developed using thinlayer chromatographic separation, and spectrophotometry. A sample solution was applied to silica gel plate, and developed with chloroform-ether (19+1). After elution with chloroform, Phthalthrin was determined by its absorbance at 282mμ.
