It is a white or pale yellow, water soluble solid.

Sodium dimethyldithiocarbamate typically crystallizes from water as the diihydrate NaS2CN(CH3)2.2H2O.

[1] Sodium dimethyldithiocarbamate is obtained by treating carbon disulfide with dimethylamine in the presence of sodium hydroxide: Other dithiocarbamates can be prepared similarly from secondary amines and carbon disulfide.

They are used as chelating agents for transition metal ions and as precursors to herbicides and vulcanization reagents.

It is a component of various pesticides and rubber chemicals in the form of its salts.
