Among 837 samples of 30 agricultural commodities tested, 43% contained residues above the detection limit for the method: 100% of broccoli samples; 80% of cabbage, kiwifruit, and grape ...
WebThe analytical method most frequently used to analyze dithiocarbamate residues in food for monitoring purposes was proposed more than 30 years ago. In this method, total dithiocarbamates are decomposed to CS(2), which is purified and reacted with a cupric reagent. The yellow complex formed is quantified by spectrophotometry. WebJul 1, 2008 · An attack of electrons from one of the β-carbons of the acetone (enolic form) to the carbon adjacent to N of dithiocarbamate group results in the formation of a new carbon–carbon bond. This becomes possible due to the formation of a positive charge on the N atom due to its protonation. Since the nitrogen atom in the dithiocarbamate moiety ...

WebA highly efficient, mild and simple synthesis of dithiocarbamates is based on the one-pot reaction of amines, CS 2, and alkyl halides without using a catalyst under solvent-free conditions. The reaction is a highly atom-economic process for production of S -alkyl thiocarbamates. N. Azizi, F. Aryanasab, M. R. Saidi, Org.
