Amino Derivatives

Abstract A Griess reaction that has been used to detect organic compounds containing an aromatic amino group was used to detect organophosphorus compounds containing a nitrophenyl group, such as ethyl parathion, methyl parathion, and fenitrothion. On reduction with stannous chloride in HCI–water (1 + 1), these compounds give respective amino derivatives, which are further diazotized and coupled with 1-naphthylamine to give intense pink–orange spots. This reagent also gives a bluish to violet spot with p-nitrophenol, a metabolite of fenitrothion. The procedure can be used to detect these insecticides in biological materials in forensic toxicology.

Potential Use

Abstract Zinc chlorlde-diphenylamlne reagent, whose use has been reported for the detection of organochlorine insecticides by thin layer chromatography, was further studied for its ability to detect the organophosphorus insecticides phorate, phosphamldon, DDVP, and phosalone and the carbamate Insecticides carbaryl and aldicarb. These Insecticides give Intense blue-green spots with this reagent. The procedure can be applied to the detection of the insecticides in biological materials and thus has a potential use in forensic toxicology
