WHITE TO OFF-WHITE CRYSTALLINE POWDER

Diethylammonium diethyldithiocarbamate is used in the synthesis of Dithiocarbamate. It serve as hosts for the specific binding of various metal cations.

Dithiocarbamate

In water-chloroform mixtures the reagent is found quantitatively in the aqueous phase at pH > 8, while it remains quantitatively in the organic phase at pH < 4.
The reagent reacts with essentially the same metal ions as does the sodium salt of diethyldithiocarbamate. However, it possesses the advantageous feature that some metal ions can be extracted with it from more acidic solutions, which in some cases may result in an increase of analytical selectivity.
The analytical applicability of several substituted dithiocarbamates has also been examined. Hulanicki demonstrated the effects of various substituents in the reagent upon the properties of the corresponding complexes. In the main the majority of analytical problems can be solved equally well with diethyldithiocarbamate itself. Substitution of the reagent enhances the efficiency of the ligand in some special cases only.
