??

Dithiooxamide acts as a chelating agent and used in the determination of copper(II), nickel(II) and cobalt(II). It is used as a building block in the synthesis of cyclen. It is involved in the preparation of thiazolothiazole-linked porous organic polymers and N,N'-disubstituted dithiooxamides. It is also employed as a modifier to prepare the modified glassy carbon electrode which is used to investigate the electrochemical properties of quercetin, an important flavonoid derivative. Further, it is involved in the preparation of chelating resin with formaldehyde, which finds application in separation and concentration of silver ions.

?? ??

Dithiooxamide is reported to form complexes with Ni(II).

Safety Profile

Poison by ingestion, intraperitoneal, and intravenous routes. When heated to decomposition it emits very toxic fumes of NOx and SOx

Purification Methods

Crystallise dithiooxamide from EtOH and sublime it at high vacuum. [Beilstein 2 IV 1871.]
