Application

Also used for colorimetric determination of small quantities of arsenic
Silver diethyldithiocarbamate may be used in the following studies:
  • Quantitative estimation of inorganic As(III) by spectrophotometric method.
  • As a colorimetric reagent for the characterization and quantification of arsenic in aqueous samples.
  • As a precursor for the synthesis of Ag2S-graphene nanocomposite.
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.

General description
