Two deuterated insecticides were prepared for use as internal standards for gas-liquid chromatographic-mass spectrometric analyses. Diethyl chlorothiophosphate-d(10) was prepared by reaction of ethanol-d(6) with P(2)S(5) to give labeled diethyldithiophosphoric acid, followed by chlorination. Treatment of the acid chloride with 3-chloro-4-methyl-7-hydroxycoumarin and potassium carbonate in acetone at
