Thiocarbohydrazide Usage And Synthesis

Chemical Properties

white to grey-beige crystalline powder

General Description

Crystalline needles and plates. Used in electron microscopy to produce electron-opaque deposits for ultra structural analysis.

Reactivity Profile

Thiocarbohydrazide is a thioamide, which may behave as a weak base and therefore will react with acids forming salts with production of heat. Thiocarbohydrazide 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

High oral toxicity.

Fire Hazard

When heated to decomposition Thiocarbohydrazide emits very toxic fumes of nitrogen oxides and sulfur oxides.
