Usage

General Description

Crystalline solid. Used as a plasticizer, as a rubber accelerator, and as an intermediate in manufacturing of pesticides.

Air & Water Reactions

pH of the saturated aqueous solution is 5.8.

Reactivity Profile

Dithiobiuret is a thioamide, which may behave as a weak acid in solution and therefore will react with base foeming salts with production of heat. Dithiobiuret may react with acids and reducing agents to form toxic hydrogen sulfide gas. This may be vigorous depending on the nature of the reducing agent. Organic amides/imides react with azo and diazo compounds to generate toxic gases. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Health Hazard

The material is highly toxic. It may cause respiratory failure.

Fire Hazard

When heated to decomposition, Dithiobiuret emits highly toxic fumes of oxides of sulfur and nitrogen.

Safety Profile

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