Description

General description

Sodium diethyldithiocarbamate trihydrate is a chelating agent, generally used in mobilizing toxic metals from the human tissues and experimental animals. It exists as a white or colorless solid, and is freely soluble with gradual decomposition.

Application

Sodium diethyldithiocarbamate trihydrate was used during the synthesis of N-allylpeptides, in a study outlining the strategy to synthesize and purify a hydrogen bond surrogate (HBS) α-helix in ∼1 week.

Spin trap used in conjunction with Fe2+ to detect NO in brain, kidney, liver, and other tissues. Simultaneous direct measurement of NO* and pO2 has been reported. A copper chelator, it has been used to quantitate copper in biological materials by ESR and is an inhibitor of superoxide dismutase, ascorbate oxidase, and other enzymes.

Biochem/physiol Actions

Inhibits induction of macrophage nitric oxide synthase.

Other Notes

Reagent used for the extraction of trace metals into organic solvents for atomic absorption spectroscopy; Precipitation of trace metals for x-ray fluorescence spectroscopy
